MOLTEN COINS Hold & Win

5 prize lines: 3 rows and both diagonals. Line pays are multipliers of the per-line bet (total bet ÷ 5).

MINI, MINOR and MAJOR land as symbols during the bonus. GRAND pays for filling all 9 cells and is added after multipliers.

Each coin carries a value drawn when it lands, as a multiple of the total bet.

• Bonus trigger: 3 or more Coin/Mystery symbols anywhere start the Hold & Win bonus. Triggering symbols stick with their landed values. Line wins from the same spin are also paid.
• Respins: start with 3. Any new landing resets respins to 3. The round ends at 0 respins or a full 9/9 grid.
• Volcano Eruption: randomly on a base spin, the volcano overwrites 1–3 non-special cells with new Coin/Mystery symbols. It runs before line evaluation, so it can break a line or complete a trigger.
• Collect: gathers the current values of all coins and jackpot symbols on screen the instant it lands. It does not collect from other Collect cells, and an unresolved Mystery contributes 0.
• Mystery: resolves at the very end of the bonus into a coin value or a jackpot symbol, before multipliers apply.
• Multiplier cells: x2 / x3 hold a grid position and multiply the final coin + jackpot + collect total (product capped at x12). GRAND is added after and is not multiplied.
• Buy Bonus: pay the listed price to trigger the bonus instantly. No line wins are paid on a bought bonus.
• Max win: 5000× total bet per round.

• Provably fair: every spin commits to a hashed server seed; verify any spin to replay the full round from the revealed seed.
• All game math is server-side; the browser only replays results.
• Requests are HMAC-signed with timestamp drift limits and idempotency keys.
• Money is handled in integer subunits end-to-end.
