📖 THE BOOKS · MAINNET 4663

Don't trust us. Check.

Every game result comes from a blockhash that did not existwhen you placed the bet — so neither we nor anyone else could know or steer it. That makes every settlement re-derivable. This page shows you the live house balance, the exact payout tables stored in the contract, and a verifier that recomputes any bet's payout from scratch.

What the house is holding and what it owes

Reading the chain…

🧾 YOUR STAKE PROOF

See exactly what you hold and earn, straight from the contracts

This reads the contracts, not our database. You get the same numbers anyone could fetch themselves, quoted as of a specific block so the proof is reproducible.

🔍 BET VERIFIER · RECOMPUTE ANY SETTLEMENT

Check a payout yourself

You wager at block N. The outcome comes from a blockhash that does not exist yet at that moment — so nobody, including us, can know or steer it in advance. Enter a bet id and we re-derive the result from the stored blockhash and compare it against what the contract actually paid.

❓ HOW THE FAIRNESS WORKS

Commit, then reveal — in plain terms

  1. You place a bet. Your wager is locked at block N, and the contract records that block number. At this moment the outcome is undecided.
  2. A future block decides it.Later, the settlement reads a blockhash that was produced AFTER your bet committed. Nobody — not us, not the sequencer's mempool, not you — can know that value when the bet is placed.
  3. The math is public. Plinko walks the blockhash bit-by-bit across the pegs; Crash divides a constant by the hash. Both formulas are in the contract and reproduced on this page, so the result is checkable rather than asserted.
  4. If you miss the reveal window, you get your wager back. refund() is open to you after the window closes — no stuck funds.

Honest limits: this commit/reveal scheme uses block data, not a VRF oracle. Max bet is deliberately kept modest until an oracle upgrade. We'd rather say that plainly than describe it as "unhackable".

🧪 PRACTICE FIRST

Play with worthless tokens

The arcade runs on test tokens with the identical contract math and the identical reveal. Same odds, same verifiability, zero risk. Real GMTS wagering is deliberately switched off until the reserve-safety accounting and the mobile/desktop verification pass are both signed off.
