CrashBurst — Provably Fair Crypto Crash Game · Play & Cash Out in Real Time

How Mines works

Pick a bet amount and how many mines (1–24) to hide on the 5×5 board. Then click tiles one at a time.

💎 Safe tile → multiplier grows. Keep going or cash out.

💣 Mine → round ends, you lose your stake.

🏆 Cash Out any time after the first safe pick.

5 safe picks1.92×

10 safe picks4.80×

15 safe picks19.57×

All 22 safe2185×

Risk vs reward

More mines = fewer clicks before hitting one, but bigger multipliers per safe pick. A single mine pays slowly; 24 mines is a near-instant 24× bet if you guess right.

Provably fair

Mine positions are derived from HMAC-SHA256 of our secret server seed, committed to you as a hash before the round starts. When the round ends, the seed is revealed so you can verify.

House edge: 5%

How HiLo works

A card is shown. Pick Higher or Equal (↑) or Lower or Equal (↓) for the next card.

✅Right → multiplier grows, keep going or cash out.

❌Wrong → lose your stake.

🟰Same rank = win for whichever side you picked. No push.

Ranks

A=1 (lowest), 2–10 face value, J=11, Q=12, K=13 (highest). Both picks are always available — on an Ace, "≥" is a guaranteed win but pays only 0.95×; "≤" pays 12.35× but only wins on another Ace. Same on the King in reverse. Use extreme cards to cash out or grind forward at a small cost.

Multiplier formula

13 / winning-ranks × (1 − 5%). Ties counting as wins means the odds are symmetric around rank 7.

Deck

Each card is drawn independently with uniform probability 1/13 across all 13 ranks. No finite shoe — past cards don't influence future draws. Every card is still deterministic from a committed server seed, so the entire sequence is provably fair after the round ends.

How Blackjack works

Beat the dealer without going over 21. Cards 2–10 = face value, J/Q/K = 10, Ace = 1 or 11.

Hit — draw another card.

Stand — end your turn, dealer plays.

Double — double your bet, draw one more card, auto-stand. Only on your first action.

How Plinko works

Drop a ball from the top. It bounces left or right 50/50 at each peg, landing in one of the colored buckets below.

Rows

More rows = more bounces = higher variance. Edge buckets become rarer but pay much more.

Risk profiles

Low — small wins, small losses. Almost break-even.
Medium — balanced swings.
High — rare big wins, frequent losses in the middle.

Top multipliers (16 rows)

Low · edges1.9×

Medium · edges10.4×

High · edges27.4×

Edge buckets on 16-row have a 1-in-65,536 chance each side — so ~1-in-32,000 to land jackpot.

House edge

5% on every combination of rows × risk. Multiplier tables are calibrated so expected return = 0.95 per $1 staked, regardless of choice.

Provably fair

Each peg decision = 1 bit from HMAC-SHA256(server_seed, client_seed:nonce). Seed hash committed before drop; full seed revealed after so you can verify the exact path.

How Wheel works

Pick your segments count and risk level, place a bet, then spin the wheel. The segment under the pointer when the wheel stops determines your payout.

Segments

10, 20, or 50 slots. More segments = more variance possible; bigger potential jackpot on high-risk 50.

Risk profiles

Low — ~70% of segments win, all modest payouts.
Medium — ~40% win, payouts vary.
High — only ~20% win, but one big jackpot.

Max multipliers

10 · High~6.7×

20 · High~11.4×

50 · High~26.8×

No fake wins

Every colored segment is a real win (multiplier ≥ 1×). If it's grey, it's a loss. No misleading partial-payout segments.

House edge

Exactly 5% on every combination. Expected return per $1 staked is always 0.95.

Provably fair

Landing segment derived from HMAC-SHA256(server_seed, client_seed:nonce). Server hash committed before spin; seed revealed after so you can verify.

How Crossy works

Pick a difficulty, place your bet, then hop your chicken across the highway one lane at a time. Every safe lane raises your multiplier. Cash out any time — or push your luck for a bigger payout.

Difficulty

Easy — 1 car in 25 lanes. Max 23.75×
Medium — 3 in 25. Max 2,185×
Hard — 5 in 25. Max 50,473×
Daredevil — 10 in 25. Cap at 1,000,000×

House edge

Exactly 5% per round. Multiplier at lane k = C(25, k) / C(25−hits, k) × 0.95.

Provably fair

All car-hit lanes are picked at round start using HMAC-SHA256(server_seed, client_seed:nonce:crossy). Server seed hash is committed before you jump, full seed revealed after the round so you can replay any hop exactly.

Cancel

If you haven't jumped yet, you can cancel for a full refund.

How Baccarat works

Two hands are dealt — Player and Banker. You bet on which one wins. Neither is "your" hand — you just predict the outcome. Tie is a third option if you think they'll land equal.

Scoring

Card values: A = 1, 2–9 face value, 10/J/Q/K = 0. Hand total is the sum modulo 10 — so 9+7 = 6, not 16.

Drawing rules

No decisions from you — the dealer follows a fixed rule table. Both hands stand on a "natural" (8 or 9 on first 2 cards). Otherwise Player draws a third on 0–5, and Banker's draw depends on their total plus Player's third card.

Payouts

Player — 1:1 · edge ~1.3%
Banker — 0.95:1 · edge ~1.1% (5% commission, still the best bet)
Tie — 8:1 · edge ~14% (high payout, high house edge)

Player/Banker bets push (stake returned) on a Tie — only the Tie bet loses in that case.

Provably fair

Each hand's 52-card deck is shuffled deterministically from HMAC-SHA256(server_seed, client_seed:nonce:baccarat). Seed hash is committed before the deal and the full seed is revealed after.

How Snake works

A 12-cell circular board. Each cell is either a multiplier or a snake 🐍. Roll two dice, the token advances by the total (2-12), and you land on a cell.

✅Multiplier cell → your running multiplier compounds. Roll again or cash out.

🐍Snake cell → round ends, lose your bet.

↩Haven't rolled yet? Cashout refunds your bet — no wagered/rakeback counted.

Difficulty

Easy1 🐍 · ~1.04× avg

Medium3 🐍 · ~1.27× avg

Hard5 🐍 · ~1.63× avg

Expert7 🐍 · ~2.28× avg

Master9 🐍 · ~3.80× avg

Average multiplier on winning cells. Higher difficulty = fewer wins but much fatter payouts; chain multiple rolls to compound.

House edge

Exactly 5% per roll. The cell multipliers are calibrated from the seed so that (12-snakes)/12 × average_multiplier = 0.95 at every difficulty.

Provably fair

Board layout and each dice roll come from HMAC-SHA256 streams on the committed server seed. Revealed after round end so you can verify every outcome.

How Tarot works

Three face-down tarot cards. Pick a bet and a difficulty, then fate decides. Cards flip in order middle → left → right to reveal your multipliers.

Middle — Major Arcana. The base multiplier, always positive. Big card, big feelings.

Left — Minor Arcana. Can boost, halve, or wipe (0×) the round.

Right — Minor Arcana. Seals the final outcome. Same distribution as the left.

Final payout

bet × left × middle × right

Difficulty

Easymax 20× · ~10% bust/side

Mediummax 160× · ~20% bust/side

Hardmax 1,176× · ~35% bust/side

Expertmax 5,000× · ~50% bust/side

If either side card reveals 0×, the round busts and your bet is lost. Expert mode is brutal — half of all side cards are busts.

House edge

Exactly 5%. Minor Arcana distribution has mean 1.00 and Major Arcana has mean 0.95, so E[L × M × R] = 0.95 at every difficulty. Max-win caps are fixed per mode.

Provably fair

Three independent HMAC-SHA256 streams — one per card slot. Server seed is hashed and committed before you play; revealed after so you can recompute every card locally.

How Keno works

Pick 1 to 10 spots from a 40-number grid. Then 10 numbers are drawn at random. Your payout depends on how many of your picks were drawn — the more hits, the bigger the multiplier.

Tap numbers on the grid to pick them. Tap again to deselect.

Random Pick fills your selection with uniformly random numbers.

Clear resets your picks.

Play draws 10 numbers and pays based on the paytable.

Difficulty

Mediumfatter tail

Highmax volatility

Low mode pays something even on a few hits — steady drip. High mode pays only on near-perfect results, but those payouts are enormous (up to ~368,000× on 10/10).

Math

10 balls drawn from 40. Probability of h hits when picking k spots follows the hypergeometric distribution: C(k,h) · C(40-k,10-h) / C(40,10). Paytables are calibrated so E[payout/bet] = 0.95 for every (difficulty, spots) combo.

House edge

Flat 5%, same as every game on the site.

Provably fair

The 10 drawn numbers come from a partial Fisher-Yates shuffle driven by a single HMAC-SHA256 byte stream keyed on the committed server seed. Revealed after each round so you can replay the draw locally.

How Dice works

A 100-sided virtual dice rolls a number between 0.00 and 99.99. Set a target and pick Over or Under. You win if the roll falls on your side.

Drag the slider or type the target directly.

Tap Over / Under to flip direction.

Multiplier + win chance update live as you move the target.

Payout formula (5% edge)

multiplier = 0.95 / win_chance

Example targets (Over mode)

target 694% win · 1.01×

target 50.549.49% · 1.92×

target 8020% · 4.75×

target 990.99% · 95.96×

target 99.980.01% · 9500×

House edge

Flat 5%, same as every game on the site. Your expected payout per $1 bet is $0.95 regardless of the target you choose — picking a low target doesn't make you win more overall, it just distributes the wins differently (more frequent smaller wins vs. rare huge wins).

Provably fair

Each roll is an unbiased integer in [0, 10000) sampled from an HMAC-SHA256 byte stream keyed on serverSeed:clientSeed:nonce, using rejection sampling to avoid modulo bias. The server seed is hashed and committed before the roll; revealed after so you can replay the exact roll locally.

How Gems works

Place a bet, five gems roll out of 7 possible colors, and the resulting combination of matches decides your payout. Think poker dice, but with shiny gems instead of pips.

Seven colors: Ruby, Topaz, Emerald, Sapphire, Amethyst, Diamond, Onyx.

Five gem positions. Each is sampled independently.

Odds

With 7 colors over 5 positions there are 7⁵ = 16,807 possible rolls. Pair is the most common outcome (~50%), but its 0.09× payout means you lose on pair. Two Pair or better returns profit.

House edge

Flat 5%. The paytable is calibrated so E[payout / bet] = 0.95 exactly — same edge as every game on the site. Five-of-a-kind's iconic 50× and Two Pair's 2× are preserved; the middle tiers are gently tuned to hit the 5% target.

Provably fair

The 5 gems come from an HMAC-SHA256 byte stream keyed on serverSeed:clientSeed:nonce. Server seed hashed pre-roll, revealed post-roll.

How Horses works

Six horses line up at the gate. Each has different odds — long shots pay big, favorites pay small. Pick one, place your bet, watch the race. If your horse wins, you're paid bet × odds.

Odds & payouts

Odds vary by race — the game draws from several probability profiles, so some races have a clear favorite (heavy chalk + long shots) and others are tight packs. Typical range: 1.7× to 47×.

Expected value is identical for every horse — picking the favorite isn't mathematically better than picking the long shot, just safer.

The race

Animation runs ~11–14 seconds. The outcome is locked in the moment you click Start — you're watching a replay of the already-decided race, not influencing it.

House edge

Exactly 5%. Odds are set as (1 − 0.05) / win_probability, then rounded to 2 decimals.

Provably fair

Each race's winner, finish times, and horse lineup are derived from HMAC-SHA256(server_seed, client_seed:nonce:subnonce). Server seed hash is committed before the race, full seed revealed in the result so you can replay the exact race deterministically.
