One rule: The multiplier grows as you dig. A cave-in can happen at any moment. Cash out before it hits.
Theoretical RTP: 93.5% for fixed cash-out targets from ×1.01 to ×9999.99. Actual session results vary. The ×10000 limit ends the round before cash-out. Calculation uses full precision; displayed multipliers are rounded.
Before each round, a SHA-256 commitment is published. After the cave-in, the seed and result are revealed. Verify checks the hash and multiplier. This is a local demo with browser-accessible data and no server protection.
