Chips paid per way at a bet of 20. A symbol pays when it shows on three or more reels in a row starting from reel 1, in any rows, and the ways multiply: two on reel 1 and two on reel 2 make four ways. The dimmer figures are payouts smaller than the bet. The Wild lands on reels 2, 3 and 4 and stands in for every paying symbol. The Mallet and the Waterwheel pay nothing themselves.
What the buildings pay
| Building | Chips | Jackpot chance |
|---|---|---|
| Reed hutJackpots: None | 10 to 40 | 0% |
| Timber lodgeJackpots: Mini, Minor | 40 to 160 | 4.0% |
| Stone lodgeJackpots: Mini, Minor, Major, Grand | 200 to 5,000 | 7.8% |
65% of all buildings are reed huts and 73% of all buildings pay two bets or less. A Mallet on a screen that is already all stone pays 200.

What collecting and upgrading really pays
Timber & Stone is a free Huff N' More Puff alternative: our own slot machine, built to play the way Light & Wonder's Huff N' More Puff plays.
Five reels, three rows and 243 ways. 6 or more Mallets start 6 free games with a frame on every position a Mallet landed on, each further Mallet raises its frame a level, from reed to timber to stone, and when the free games end every frame becomes a building that pays one prize. 3 or more Waterwheels spin a wheel that awards a jackpot or one of three ways into the free games. If you came looking for a free game like Huff N' More Puff, this is that mechanic. It is not the original, and it is not made, licensed or endorsed by Light & Wonder. The name, the beaver colony, the art, the sound, the reel strips, the weights and the pay table are ours.
Reed frame

0.5 to 2

Timber frame

Stone frame

6 or more Mallets on one paid spin start 6 free games with a reed frame on each of their positions. A Mallet that lands on a frame in a free game raises it one level. Each building pays one prize, when the free games end.
What is different from the original, and from any real machine, is everything a real machine leaves out.
This one returns 95.73% of the chips bet on it and keeps 4.27%. 26.0% of spins pay something, and 45% of those pay less than the spin cost, so only 12.4% of spins leave you with more chips than before. About 51.3% of the return comes from the ways on ordinary spins and the rest from features that start on about 1 spin in 98. The status line under the reels and the coach on the machine tell you what each round did to your stack.

Shares of everything the machine pays back. A feature starts on about 1 spin in 98. 26.0% of spins pay something, and 45% of those pay less than the spin cost.
There is no decision in a slot to get better at.
What this page is for is entertainment, and seeing clearly what a collect-and-upgrade machine does: how Mallets that are not kept look like progress, how a screen full of frames mostly pays small prizes, what the jackpots' odds are, and what buying a feature costs.

From 3 or more Waterwheels on a paid spin. The wheel awards a feature 56% of the time and a jackpot the rest.
- Five reels, three rows and 243 ways. A spin costs 20, 40, 100 or 200 chips.
- A symbol pays when it shows on three, four or five reels in a row, starting from reel 1, in any rows. The ways multiply: the number of matching symbols on each reel in the run, multiplied together.
- There are eleven paying symbols. Beaver is the highest: on five reels it pays 15 times the bet for each way. Cattail is the lowest: on three reels it pays 0.25 times the bet for each way, which at a bet of 20 is 5 chips back on a 20 chip spin.
- The Wild appears on reels 2, 3 and 4 only and stands in for every paying symbol. It does not stand in for the Mallet or the Waterwheel, and those two pay nothing themselves.
- 6 or more Mallets anywhere on a paid spin start 6 free games, with a reed frame on every position a Mallet landed on. Fewer than 6 start nothing, and nothing is kept for the next spin.
- A frame stays on its position for the whole feature. Every Mallet that lands in a free game raises the frame on its position one level: no frame to reed, reed to timber, timber to stone. The ways pay on every free game.
- A Mallet that lands on a position that is already stone puts a new frame on a random empty position. If no position is empty it raises a random frame that is not yet stone, and if the whole screen is stone it pays 10 bets.
- 3 or more Mallets on one free game add one more free game, up to 30 in a feature.
- When the free games end, every frame becomes a building and each building pays one prize. A reed hut pays 0.5 to 2 bets. A timber lodge pays 2 to 8 bets, or the Mini, the Mini twice, or the Minor. A stone lodge pays 10 to 250 bets, or the Mini, the Mini twice, the Minor, the Major or the Grand.
- 3 or more Waterwheels anywhere on a paid spin spin the wheel once. It awards the Mini, the Mini twice, the Minor, the Minor twice, the Major or the Grand, or one of three features. If a spin shows both 3 Waterwheels and 6 Mallets, the wheel is spun and the Mallets start nothing.
- Log Run: each Waterwheel, starting with the one furthest right, rolls right along its row to the edge of the screen. Every position it crosses, its own included, is treated as a Mallet landing there, so rows crossed twice go up a level. Then 6 free games.
- Great Mallet: one block of 2 by 2, 3 by 3 or 5 by 3 positions lands, and every position under it gets a reed frame. Then 6 free games.
- Stone Works: a stone frame goes on each Waterwheel's position, and in the 6 free games that follow every Mallet builds in stone at once.
- Either the free games or a spin of the wheel can be bought for 47.5 bets, which is 950 chips at a bet of 20. A bought feature starts from a screen drawn the same way as the paid spins that start it.
- No round pays more than 6,000 times the bet.
- Turbo shortens the animation. It does not change the odds, the return or any result, and it does not shorten the confirm step before a buy.
- The whole round is decided when Spin or Buy is pressed. The animation plays it back and cannot change it.
Sound starts on, and the Sound button switches it off. Turbo is off until you switch it on.

FAQ
- Is this slot played for real money?
- No. The table uses play chips that have no value, cannot be bought, and cannot be cashed out or exchanged for anything. If you run out, you are handed another stack for free. There is no account and nothing to download.
- What is the RTP of Timber & Stone?
- 95.73%. That is the share of all chips bet that the machine pays back on average, so it keeps 4.27%. The return from the ways is counted exactly and the features are simulated over 10,600,000 rounds, which leaves a sampling error of about 0.01 points on that figure. At the smallest bet of 20 chips it works out at about 85 chips per 100 spins on average, with very wide swings around it in any one session.
- How often does it pay?
- 26.0% of spins pay something, about 1 in 4. But 11.7% of spins pay less than the bet, which is a net loss that looks like a win. Only 12.4% of spins, about 1 in 8, pay more than they cost. The free games start on about 1 spin in 168 and the wheel on about 1 spin in 233.
- Is Timber & Stone a free alternative to Huff N' More Puff?
- Yes. It is built like Huff N' More Puff: five reels, three rows and 243 ways, a wild on reels 2, 3 and 4, a collect symbol that starts free games at 6 or more and frames its positions, frames that upgrade through three levels and each become a building with one prize, a wheel from 3 or more of a second symbol, and four jackpots. It is free, it needs no account, and it is played with chips that have no value. It is not Huff N' More Puff itself, which is Light & Wonder's game, and it is not made, licensed or endorsed by Light & Wonder.
- How is it different from Huff N' More Puff?
- The mechanic is the same family and everything else is our own: the name, the beaver colony on a river, the art, the sound, the reel strips, the prize weights and the pay table. So the numbers are different too. Timber & Stone returns 95.73% with a 26.0% hit rate, and those are this machine's figures only. They say nothing about the original's. The other difference is what sits beside the reels: the published odds of every jackpot and every wheel outcome, a status line that calls a payout smaller than its cost a loss, and a session coach.
- What are the odds of the jackpots?
- Per paid spin, counting every way a jackpot can be won: Mini about 1 spin in 336, Minor 1 in 3,236, Major 1 in 34,274 and Grand 1 in 208,163. At a spin every five seconds, the Grand's odds are about 289 hours of spinning on average. All four jackpots together are 16.5% of what the machine pays back, and they are fixed amounts: Mini 20, Minor 100, Major 1,000 and Grand 5,000 times the bet.
- Do the Mallets I have landed carry over to the next spin?
- No. Outside the free games nothing is collected. The outline under a Mallet on an ordinary spin is not a frame and it is wiped when the next spin starts. It takes 6 Mallets on one spin, which happens about 1 spin in 168. About 46% of spins show at least one Mallet and start nothing, and a screen exactly one Mallet short comes up about 1 spin in 73. Inside the free games frames are kept, but only until that feature ends.
- How much do the buildings pay?
- Mostly small prizes. 65% of all buildings are reed huts, which pay 0.5 to 2 bets, and 73% of all buildings pay two bets or less. A free games feature from 6 Mallets ends on average with 6.5 reed huts, 2.7 timber lodges and 0.8 stone lodges. The stone lodges, which pay 10 to 250 bets or a jackpot, carry about 51% of that feature's average value, from fewer than one building in it.
- Is buying the feature better value than spinning?
- About the same, and much faster at spending chips. A bought feature costs 47.5 bets. Bought free games return 95.92% of the price on average and 71% of them pay back less than they cost. A bought wheel spin returns 95.93% and 78% of them pay back less than they cost. The wheel awards a feature 56% of the time and the Mini, once or twice, 40% of the time. One buy puts 47.5 spins of stake at risk in a few seconds.
- Does turbo change the odds?
- No. Every spin is drawn the same way and the return stays 95.73%. What turbo changes is speed: more spins fit into an hour, and the cost of an hour is the number of spins times the 4.27% the machine keeps on each. The coach says so while turbo is on.
- Can I tell when a feature is coming?
- No. Each reel stops on its own, every stop on a strip is equally likely, and a spin starts from nothing. A run of blank spins does not make a feature due, and five Mallets or two Waterwheels are not a sign of anything: that spin is worth what its ways paid and nothing more.
- What is the most a round can pay?
- 6,000 times the bet. The engine holds every round to that cap, and the largest single prize is the Grand at 5,000 times the bet. A round that pays 100 times the bet or more comes up about once in 1,141 spins. Almost all rounds pay far less, and most pay nothing.
How this game works
Each reel is a fixed strip of symbols, 74, 78, 78, 78, 74 symbols long from reel 1 to reel 5 on a paid spin, with separate strips of 73, 76, 77, 76, 73 for the free games and a third set for the Stone Works. A spin picks one stop on each strip with your browser's random number generator, every stop equally likely, and the three symbols from that stop down are what shows. Building prizes and the wheel's outcome are drawn from weight tables that are printed in the code this page runs and shown under the machine. There are 2,598,646,752 ways the five reels can stop on a paid spin.
Part of the 95.73% return is counted and part is simulated, and the two are kept apart. The ways on a paid spin return 49.09% of the bet, and the chance of the free games (0.596%) and of the wheel (0.430%) are exact: the reels stop independently, so those are sums over the strips with no sampling. What a feature pays cannot be counted that way, because frames build on each other across free games. So the features were simulated over 10,600,000 rounds from a fixed seed, through the same code the machine plays with, and each kind of feature was weighted by its exact chance. An automated test reruns a shorter simulation from the same seed, and plays over a million whole rounds straight through the engine, and requires both to agree with the stored figures. The house edge on the common casino bets puts the 4.27% this machine keeps in context.
Inside a simulated feature, the frames are what is sampled. Each building's prize is then priced at its exact average from the weight tables, and what the 6,000 bet cap withheld in the sampled features is subtracted. That takes the luck of a rare jackpot out of the return figure and leaves a sampling error of about 0.01 percentage points, so the second decimal of the return is not certain. The jackpot odds are worked out the same way: the simulated number of timber and stone lodges per spin, multiplied by each lodge's exact chance of a jackpot, plus the wheel's exact chances.
Where the return comes from: 51.3% from the ways on paid spins, 28.3% from free games started by 6 Mallets, and 20.4% from the wheel, its three features and its jackpots together. Jackpots, wherever they are won, are 16.5% of the return, which overlaps the last two. 26.0% of spins pay anything, 11.7% pay something smaller than the bet, and 12.4% pay more than the bet. The spread of one spin's result has a standard deviation of 14.0 bets, which is high: long flat stretches and rare large rounds are how this kind of machine behaves.
A bought feature costs 47.5 bets and starts from a screen drawn with exactly the distribution of the paid spins that start that feature. Its figures come from the same simulation: bought free games return 95.92% of the price and bought wheel spins 95.93%, and 71% and 78% of them pay back less than the price. The wheel on screen has twelve wedges of the same size, and the Grand's is 0.03% of wheel spins. The odds of every wedge are in the table under the machine.
The expected figure in the session panel is the share the machine keeps multiplied by the chips you have staked on finished rounds, with a bought feature counted at its full price. The coach's count of spins in the last minute is taken from when you pressed Spin.
Limits
- The reel strips, prize weights, wheel weights and pay table were designed for this page. They are not a copy of Huff N' More Puff or of any other real machine, and these figures describe this machine only.
- Huff N' More Puff is Light & Wonder's game and its name belongs to its owner. Timber & Stone is an independent alternative built on the same kind of mechanic. It is not made, licensed or endorsed by Light & Wonder.
- The jackpots here are fixed amounts. Play chips have no pooled prize, so nothing on this machine is progressive, and a real machine with a jackpot that grows behaves differently.
- The feature figures are simulated, not counted, and carry the sampling error stated above. The ways and the trigger chances are exact.
- A real slot is usually shipped in several return settings and the casino chooses one. The same title can keep noticeably more than the figure quoted for it, and a real machine does not print its reel strips or its prize weights.
- The reels are stopped by an ordinary browser random number generator. It is not an audited or certified generator, and nothing here should be read as a test of one.
- Turbo is here because the machine this one is modeled on has a turbo mode. It makes a machine cost more per hour, and the coach prices the pace while it is on. Autoplay is left out because the sources do not show that the original has it.
- Buying a feature here costs chips that are free. With money, the same button spends dozens of bets in one press, and that is the part play chips cannot show.
- Play chips do not feel like money. A long blank run is harder to sit through, and to stop after, with a real stake.
This is a practice game for adults. It has no real-money play and links to none. Huff N' More Puff, or any slot played with money, keeps its share of every spin and every bought feature, and no way of timing or sizing them changes that. On this machine 45% of the spins that pay anything still cost more than they return, and 73% of the buildings pay two bets or less.
