The casino and the club

Fair games, your limits

Every result is locked in before you bet, and you can check it yourself after. And you set the limits: a daily loss limit, a break when you want one, and a reminder every hour of how long you've played.

  • Checkable results
  • Loss limits
  • Breaks

Find Fairness and Limits in the casino's top bar.

Provably fair

Locked in before you bet

Every round is . The casino commits to a secret before you bet by showing its fingerprint, then mixes it with a seed of yours. Later it shows the secret, and your browser checks the round.

The machines play your own seed, and you rotate it in Fairness to see its secret. Each room's round has a seed of its own: its fingerprint shows when betting opens, the secret once the round is paid. The Coaster locks in its whole day's chart in advance and shows each minute's secret as it ends.

Nobody, the casino included, can pick a result after seeing the bets: the secret was fixed first, and at the tables bets close before the result is worked out.

Adults only

Once, before your first bet

Stonk Tower is for players aged 18 or older. You confirm that, and that playing is allowed where you are, when you sign in: it is in the Terms of Use.

Chips can be cashed out, so before your first bet the casino asks once more, on a card of its own, that you are old enough and that gambling is legal where you are. That one confirmation covers the Stonk Exchange, paid races, tournaments and wagers too.

Once the casino opens to everyone, it follows the law where you are: in some countries it stays closed.

Your limits

Set them before you need them

All three are in the casino's Limits sheet, any time, at any table.

A daily loss limit

The most you let yourself lose in a UTC day, across every table and both wallets. A bet that could take you past it is refused.

Setting or lowering a limit works at once. Raising or removing one waits 24 hours, so a bad moment can't undo it.

Lost today60% of your limit

Room to play. The meter resets at midnight UTC.

Take a break

Close the tables to yourself for 24 hours, 7 days, 30 days or for good. It starts at once and can't be ended early.

You can still walk in and watch, and cash out your chips. Tips, the bar and buying shares wait for the break to end; selling shares never does.

No play until … UTC, and no way to end it sooner.

The reality check

After every hour of play, a card shows how long you've played, how many rounds, and where you stand. Keep playing, open your limits, or leave.

Reality check

You've played for 1 h 00 min: 84 rounds, net −1,250 chips.

An example hour. Next check in 60 minutes.

Table limits

The limits follow the house's bank

No fixed caps: the biggest win on one round is a share of the house's own $TOWER, , counted every day at 00:00 UTC. Each game's share follows its house edge. When the house wins, the next day's limits grow; when it loses, they shrink. Drag the bank:

  • Blackjack0.1% of the bankBiggest win200KBets25 – 25K
  • Roulette0.5% of the bankBiggest win1MBets25 – 27.7K
  • Baccarat0.25% of the bankBiggest win500KBets50 – 41.6K
  • Slots: Bull Run1% of the bankBiggest win2MBets2 – 2,000
  • Plinko0.25% of the bankBiggest win500KBets1 – 500
  • Coinflip0.5% of the bankBiggest win1MBets500 – 510.2K
  • The Stonk Coaster0.25% of the bankBiggest win500KBets250 – 250K

In chips, a round. The largest bet is the biggest win divided by the game's top payout; the smallest is about a thousandth of the game's largest. A room's table takes a part of its game's range, and each slot title's largest bet follows its own top win (Bull Run's is 1,000×).

  • The house winsIts bank grows, and the next day's limits grow with it.
  • The house losesIts bank shrinks, and the next day's limits shrink with it.
  • Down 1% in a daySmall stakes until 00:00 UTC: every limit is a tenth of normal.
  • The day's room: every bet still open, across the whole casino, may stand to win at most 5% of the bank at once, and one wallet's open bets 1%. A bet that would pass either is refused, with the largest that fits.
  • Payouts depend on the bank being there. If the house's bank can't be read, or is too small for a table's smallest bet, that table is closed for the day rather than run on a guess.
  • A round that is interrupted is finished by its own rules when it can be (a blackjack hand left alone stands). One that can't be finished is voided and its stake returned.

Autoplay

Only on slots and Plinko

Autoplay presses Spin or Drop for you, up to 500 rounds, each an ordinary bet with every limit applied. It never starts on its own, and never buys a slot's bonus.

It stops by itself at any refusal, at your loss limit or a break, when you hide the tab, leave or sign out, and at the reality check. Esc stops it any time.
