Coin Flip live
One coin for everybody every minute: 15 seconds to bet, then the server flips the coin once and everybody sees the same result. Heads or tails, a win pays ×1.94 incl. the stake (97 % return). W only, no money.
Chip
A coin every minute. Bets 0–15 s; at the 15th second the server picks the side once from the seed it committed in advance and settles every bet. One bet per round on one side.

Shared round. One coin for everybody, every bet is paid separately: win = stake × 1.94 rounded down to 0.0001 W (97 % return; stakes from 0.10 W in steps of 0.01 W). The seed is committed with SHA-256 at the start of the minute (before any bet) and revealed after settlement: the page repeats the hash and the flip itself.
How the side is picked. The top bit of the first byte of HMAC-SHA256(seed, rule + round ID): exactly 128 of 256 values per side. The personal Coin Flip (×2) works as before.

The seed hash is shown from second 0, the seed itself after settlement at second 15: the page repeats the hash and the flip. The server takes no bets after second 15.
The page syncs its clock with the server and shows the round from the right moment. The result is never made in the browser.
