Provably-fair games (dice, Plinko & Mines), crypto balances, and progressive must-win jackpots — all on wtf1dollar.com.
Your balance is a single USDT balance (1 USDT = $1), so bets and payouts are all in dollars. Enter your stake, pick a target between 2 and 98 and choose Roll Under or Roll Over. Each roll produces a number from 0.00 to 99.99. If it lands in your winning zone you're paid bet × multiplier. The multiplier is (100 − house edge) ÷ win chance, so a lower chance means a bigger payout. The house edge is just 1%. The minimum bet is $0.10 and the maximum is $1,000.
Drop a ball down a pyramid of pegs and win whatever multiplier the slot it lands in shows. Pick the number of rows (8, 12 or 16) and your risk level (Low, Medium or High): higher risk means smaller middle payouts but far bigger edges — up to 1000× on 16-row high. Every slot's payout is bet × multiplier, and the tables are tuned to the same 1% house edge as dice. The minimum bet is $0.10 and the maximum is $1,000, with the same optional jackpot opt-in as dice.
A 5×5 grid hides between 1 and 24 mines — you choose how many. Stake up front, then reveal tiles one at a time: every safe tile grows your multiplier, and you can cash out at any point. Hit a mine and the stake is gone. The multiplier after each safe pick is (100 − house edge) ÷ chance of surviving this far, so more mines and deeper runs pay dramatically more — a full clear on a mid mine count runs into the millions-×, hard-capped at a $50,000 payout per game. Same 1% house edge, same $0.10–$1,000 bet range, and the same optional jackpot opt-in as the other games.
There are three growing jackpots — Mini, Mega and Grand — funded the way the biggest casinos do it. Opt into any tier and a flat amount is added on top of each bet and flows into that pot (Mini $0.10, Mega $0.50, Grand $1.00 per bet). Any bet size qualifies — the contribution is simply deducted from your balance alongside your stake. A slice of every contribution is set aside in a reserve, so the moment a jackpot is won the pot instantly reseeds to a healthy starting amount — there's always a live jackpot on the board to play for.
Every round each pot has a secret must-win target — a hidden value between the pot's starting amount and its cap, locked in before the round by the pot's seed hash. As bets top the pot up, the bet that pushes it past the hidden target wins the whole pot instantly (minus a 2% house fee). Because a bigger bet contributes more, it's proportionally more likely to be the one that crosses the line — and the pot always drops at or before the cap. Right away a fresh round begins with a new hidden target.
Dice: each roll is HMAC(server_seed, client_seed:nonce). We show SHA256(server_seed) up front and you control the client seed; rotate your seed anytime to reveal the old server seed and verify every past roll.
Plinko: uses the same seed pair and nonce sequence as dice. The ball's path comes from the same HMAC(server_seed, client_seed:nonce) — bit i of the digest decides the bounce (left or right) at row i, and the landing slot is the number of right-bounces. Rotate your seed to reveal the server seed and replay every past drop.
Mines: shares the same seed pair and nonce sequence. Mine positions are locked in the moment you start a game: an HMAC byte stream keyed by client_seed:nonce:mines:n drives a Fisher-Yates shuffle of tiles 0–24, and the first m tiles are the mines. They stay secret while you play; rotate your seed to reveal the server seed and recompute the layout of every past game.
Jackpots: each round's hidden target is derived from the pot's secret seed — target = start + (cap − start) × HMAC(pot_server_seed, round:target). The pot publishes SHA256(server_seed) before the round; when the round ends the seed and target are revealed alongside the round's start value and cap, so anyone can recompute the target and confirm the winning bet was the one that crossed it — on the History page.
