Learn how to play and win at ARCade
Objective: Climb the tower by picking safe tiles. The higher you climb, the bigger the multiplier!
How It Works:
- Place your bet (0.5 - 100 USDC)
- Each row has multiple tiles, but one is a death tile
- Click a tile to reveal if it's safe or deadly
- Safe tiles let you climb higher with increasing multipliers
- Cash out anytime to secure your winnings
- Hit a death tile and lose your bet!
Multiplier Calculation:
The multiplier increases based on survival probability. Each row has a different number of tiles (3-7), making some rows riskier than others.
Multiplier = (1 ÷ Cumulative Survival Rate) × 0.9
The 10% house edge is built into the multiplier calculation.
Objective: Predict whether the dice roll will be OVER or UNDER your target number.
How It Works:
- Place your bet (0.5 - 100 USDC)
- Set a target number between 2 and 98
- Choose UNDER or OVER
- The dice rolls a number from 1-100
- Win if the result matches your prediction!
Multiplier Calculation:
Your win chance determines your multiplier. Lower probability = higher payout.
Multiplier = (100 ÷ Win Chance %) × 0.9
Example: Target 25, bet UNDER = 24% chance = 3.75x multiplier
Objective: Cash out before the cannon explodes! The multiplier rises exponentially — but crash at any moment!
How It Works:
- Place your bet (0.5 - 100 USDC)
- Optionally set an auto-cashout multiplier
- Watch the multiplier climb: 1.00x → 1.50x → 2.00x...
- Click CASH OUT to secure: bet × current multiplier
- If it crashes before you cash out, you lose!
Crash Probability:
The crash point is randomly determined each round. Higher multipliers are exponentially less likely.
~10% crash at 1.00x (instant) | Max payout: 100x
Objective: Spin the wheel and hope it lands on a high multiplier to win big!
How It Works:
- Place your bet (0.5 - 100 USDC)
- Click SPIN to start the wheel
- The wheel has 20 segments with different multipliers
- Wait for the wheel to stop on your segment
- Win instantly if it lands on a multiplier!
Segment Distribution:
- 0x (Loss): 8 segments (40%)
- 1.5x: 4 segments (20%)
- 1.8x: 3 segments (15%)
- 2x: 2 segments (10%)
- 3x: 2 segments (10%)
- 5x (Jackpot): 1 segment (5%)
Objective: Dodge lasers on a shrinking 10×10 grid. Survive as many rounds as possible!
How It Works:
- Place your bet (0.5 - 100 USDC)
- Click any cell on the grid to dodge the laser
- Odd turns destroy a COLUMN, even turns destroy a ROW
- If your cell is in the destroyed row/column, you lose!
- Survive to increase your multiplier
- Cash out anytime after surviving at least one round
Multiplier Ladder:
The multiplier increases exponentially as you survive more turns:
Turn 1: 1.06x → Turn 10: 3.83x → Turn 18: 95.9x
The grid shrinks after each attack, making survival progressively riskier!
