How the machine works

The fees — 4.2%, the same for everyone

A spin costs 4.2% of your deposit's value, taken once, up front:

• 1% burned forever — sent to the dead address.
• 3% into the prize budget — every cent comes back to spinners, as instant multipliers and as The Pot.
• 0.2% buys and burns $TDM — the only slice that doesn't come back, which is why it's kept this small.

There are no fee tiers, and no way to pay less than anyone else. There used to be: holding $TDM discounted the $TDM slice. When that slice dropped from 1% to 0.2%, the best possible discount became about five cents on a $25 spin, so the tiers were removed instead of kept as decoration. The 0.8% went into prizes instead, which is part of what funds the paytable below.

Holding $TDM now pays through season emissions instead: your spin volume counts for more when you hold, so you earn a bigger share of the season's $TDM budget. That budget is fixed, so a multiplier changes how it's divided and never how much is printed — and it leaves the game itself untouched. Same price, same odds, for every wallet.

Your prize basket is worth exactly 95.8% of your credited deposit, and you receive it in full — no fee at claim, no fee on the way out, ever. There is no machine fee and no randomness fee — the 4.2% is the whole cost.

On a $25 spin that's 25¢ burned, 75¢ to prizes, and 5¢ buying and burning $TDM.

What a spin can hit

Every spin lands in exactly one band, and the bands add to 100%:

• 5.88% — 1.42× (Nice, +$36.04 on a $100 spin)
• 94.1% — 1× (Your basket, in full)

On top of every one of those, the same spin is also a live ticket for The Pot — one ticket per dollar credited, drawn at 1 in 12,000,000 tickets — and guaranteed to drop at least every 7 days no matter how quiet the machine is.

Odds are flat per spin. Expected instant payouts total 2.47% of credited value against the 2.51% funding them, so the prize budget can never go negative.

The Pot

0.6% of every spin accrues to a single shared pot. One spin takes the whole thing — not a multiple of your deposit, the entire accumulated balance. At current volume it reaches roughly $60K and is taken about once a month.

Your odds scale with your spin. One ticket per $1 of credited value, drawn at 1 in 12,000,000 tickets — so a $100 spin is 1 in 120,000. It has to work this way: with flat per-spin odds, people would grind minimum spins to farm a pool-sized prize.

The Pot can never pay more than it holds, so it is solvent by construction. A round runs for at most 7 days; if nobody has drawn it by then, the next spin takes it whatever it happens to be worth. It was seeded with $6,900 at launch so it started at a real number — that seed is disclosed here rather than presented as accrued volume.

Why a time limit and not a dollar one. A pot is accrual × volume × time. Cap the dollars and you fix the prize while the cadence drifts with volume — a ceiling that drops monthly at heavy volume takes over a year at launch volume. Cap the time and you fix the cadence while the prize grows with the machine. The second is the one worth promising, because it is true on day one.

Tokenomics — $TDM

Fixed 1.00B supply and zero pre-allocation of any kind. $TDM launches on the pons launchpad, which mints every token straight to its bonding curve — there is no mechanism by which a team bag could exist. We buy the 22.5% the machine needs off that curve at launch, same price as everyone, and publish the transaction.

Emissions (200.00M) are earned, never sold. They pay out across 8 seasons, each with a fixed budget shared pro-rata by spin volume — your share is your volume divided by everyone else's that season.

That structure is deliberate. A fixed per-dollar rate would either drain the reserve during a busy month or trickle out forever; a halving schedule asymptotes, so most of the reserve would never reach anyone. A fixed seasonal budget can't be over-emitted at any volume, and it self-adjusts — a quiet season simply pays more $TDM per dollar spun. Budgets decline across seasons because the earliest users take the most risk.

$TDM has two jobs: it multiplies the season emissions you earn (see the tier table above), and 0.2% of every spin buys it on the open market and burns it. Full detail on the $TDM dashboard.

No losses disguised as wins

On a modern slot machine, roughly 60% of celebrated “wins” pay back less than the wager — the machine plays win sounds over what is actually a loss. The industry calls them losses disguised as wins, and the UK Gambling Commission banned them in 2021.

The machine has none. A spin costs 4.2% at base, so break-even sits at 1.044× — and our smallest tier is 1.42×. Every multiplier we celebrate leaves you ahead.

It also means our headline hit rate is lower than a casino's, and that's the point: a slot advertising 33% is really paying out about 14% of the time. Ours pays 5.9% of the time, for real, every time.

The small-cap discount

Tokens under $10M market cap are credited at 97% of quoted value. Everything above that is credited in full. One number, one threshold.

Small-cap tokens are cheap enough to move that their price can be nudged, and the discount absorbs that gap. This replaced a size-scaled formula that was mathematically neater and impossible to explain — a number people can remember beats a curve nobody reads.

Nobody collects it. Your full deposit still enters the prize pool, so the discounted slice stays there as extra backing behind everyone's prizes. As a token grows past $10M, its discount simply stops applying.

How the randomness works

Your spin is sealed into one block, and decided by the hash of the next one. At the moment you pay, the block that picks your prize does not exist yet — so there is nothing for us, for you, or for a bot to read, simulate, or reroll. Once it lands, anyone can recompute the result from the block hash and your spin id and check it matches. That takes about a second, which is the spin animation.

The honest limit: whoever produces the reveal block could, in principle, vary its contents and re-roll. On Robinhood Chain that party is the chain's own sequencer, and we've judged that operator grinding blocks to win memecoin baskets isn't a credible threat for launch. It's stated here rather than buried, and the randomness source sits behind a swappable interface — the day a verifiable-randomness provider deploys natively on this chain, it drops in without touching the vault.

Limits that protect the pool

Two rules exist to stop a thinly-traded token being used to price something it can't actually clear. Neither one is discretionary — both live in the contracts.

• A spin can't exceed 2% of its token's DEX depth. Market cap says what a token is nominally worth; only pool depth says how much of it can be priced. A coin with $122k of liquidity caps out around $2,400 a spin — far above anything an ordinary spinner will hit, and far below the size where a quoted price stops being real.
• Stale numbers fail safe. Every listed token carries a last-updated stamp. If its market cap hasn't been refreshed within a week, the machine stops trusting the figure and applies the small-cap discount automatically. The dangerous case is a token that has fallen below the threshold since we last looked — it would otherwise credit at full value while being cheap to nudge. Our neglect costs you a 3% discount; it never costs the pool.

What we can and can't change

The honest version of a trust page is a list of the keys that exist. Here is ours.

The last row is the one to watch, and we'd rather say so than let you find it. Whoever holds that key can point the price feed anywhere, which is the same as holding the pool. It goes behind a timelock or multisig before real money is involved.

The closed loop

You can only win tokens other users deposited. The protocol holds no house liquidity, takes no directional positions, and never sells anything. Prize odds track the square root of inventory — enough for the pool to self-balance, without making the most-dumped token the one you're likeliest to win.

Risks, plainly

• Memecoins are extremely volatile. Equal value at spin time is not equal value an hour later.
• Smart contracts can have bugs. Contracts are audited before mainnet; audits reduce risk, they don't eliminate it.
• You're trading which token you hold, randomly. Never spin more than you can afford to hold in any whitelisted token.
• Nothing here is financial advice.
