6×5 cluster pays · 8+ matching flowers anywhere win and tumble
8 or more matching flowers anywhere on the 6×5 board pay, burst, and new flowers rain in. Tumbles repeat as long as new wins land (up to 10 per spin), and every tumble's win is added to the spin total.
Rainbow flowers carry a multiplier of x2, x3, x5, x8, x10, x15, x20 or x25. They stay on the board for the whole spin — at the end of the spin, all visible rainbow multipliers are added together and the sum multiplies the spin's total tumble win (capped at x100 per spin).
Land 4+ scatters on a spin to trigger free spins: 4 scatters pay 2× and award 10 spins, 5 pay 5× and award 12, 6+ pay 50× and award 15. 4+ scatters on a free spin retrigger +5 more. Rainbow flowers appear far more often during free spins.
Bonus Buy (12.3× bet) buys 10 free spins and Super Buy (31.7× bet) buys 12 free spins with boosted rainbow multipliers — the buy plays as the first of your free spins. Double Chance raises the bet to 1.25× and boosts scatter frequency on paid spins.
Bets are typed OSRS-style — 10m, 250m, 1b. Minimum bet 1M, maximum bet 1B — and no single wager (including a Bonus/Super Buy's total cost) can exceed 1B. The maximum win is 2,000× bet per spin, capped at an absolute payout of 30B.
Every spin is provably fair: its outcome derives from HMAC-SHA256(serverSeed, clientSeed:nonce), committed by a public hash before you spin. You have your own client seed and can rotate to a fresh pair anytime — rotating reveals the old server seed so past spins can be verified. Open the shield button in the bottom bar.

Each spin's entire outcome comes from a committed seed pair — verify it anytime.
Server seed (SHA-256 hash)
Client seed
Nonce (spins with this pair)
New client seed (optional, used on rotate)
After rotating, compute roundSeed = HMAC-SHA256(revealedServerSeed, clientSeed + ":" + nonce) (hex). Seed an sfc32 PRNG with the four big-endian uint32s of its first 16 bytes, discard 12 warm-up draws, then replay the spin: the game fills the 6×5 board row-major and draws every tumble refill and rainbow multiplier from that same stream. The PRNG is exposed as window.FlowerPartyFair.rngFromSeedHex(roundSeed) in this page's console, and the full engine is view-source.
