HiLo

There is no deck to trust, because there is no deck. The chain produces verifiable randomness (Chainlink VRF on Arbitrum, Switchboard on Solana — committed before your bet and verified at reveal), and each draw is ONE division of it: rank = randomness mod 13 + 1. Take the published value, run the same division, and you get the same rank. The price of a seat is ⌊99·13/ways⌋ percent, where ways is how many of the thirteen ranks win it — the shaded run on the strip is literally that numerator — from a table generated from a single source and compiled into the program. That floor is the honest part: a call has one payout knob and the label grid is 0.01×, so the return lands at 99% or just under it, never above. Seats therefore differ a little — 98.46% to 99.00%, a house edge of 1.00% to 1.54% — and each button prints its own figure.
