Betting rules

Last updated: August 2026

Fairness

Every game is provably fair. Outcomes are generated on our server using a cryptographically-strong RNG (Python's secrets module). Every bet is logged in a permanent audit trail — for any dispute, email support@dolla.fo with your username and the approximate timestamp and we'll pull the exact server outcome.

Individual game payout formulas are listed below (see each game section). Session results vary widely — that's the nature of chance-based play.

Bonus rules

Every deposit above $10 receives a 200% match bonus, capped at $500. The bonus is credited immediately but locked from withdrawal until the wagering requirement is met.

Cashout requests

Cashouts are handled manually. Click the Cash Out button in the top bar, which opens the Telegram bot and starts a cashout conversation with our team. Turnaround: usually under 24 hours during working days.

Game-specific rules

Full mechanics for each game are visible in-game via the ⓘ button in the top-right of any game modal — including payout formulas, chance tables, and specific limits.

Dice

Pick a target 2–98 and a direction (over/under). The server rolls a random number in [0, 100). Lower win chance → higher payout multiplier.

Crash

Set your auto-cashout multiplier (minimum 2×). A hidden crash point is rolled server-side; if it exceeds your target, you win at that target. Small chance of an instant-bust at 1.00×.

Limbo

Set a target multiplier (minimum 2×). If the rolled multiplier meets or exceeds your target, you win at that target. Higher targets pay bigger but hit less often.

Plinko

Choose risk level (low/medium/high) and rows (8/12/16). Ball performs a true 50/50 walk down the pegs; bucket determines your payout multiplier. High-risk edge buckets can pay hundreds of times your wager.

Mines

25-tile grid, you choose 1–24 mine positions. Reveal safe tiles to grow your multiplier; cash out any time. Hit a bomb, lose the wager. All bomb positions are chosen server-side before any tile is clickable — the client never sees them until bust or cashout.

Hi/Lo

Draw a card from a 13-card deck (Ace-low). Guess whether the next card is higher or lower; ties trigger a redraw. Each correct guess compounds your multiplier. Cash out any time.

Disputes

All bets are logged in a server-side audit trail (the bets table). For any dispute, email support@dolla.fo with your username and the approximate timestamp — we can pull the exact server outcome and RNG record for that bet.
