Slot Summary

Locking the fifteenth position is the decisive action in Coins & Diamonds: Hold and Win, since a full board awards the 5000x Grand Jackpot. Octoplay uses a 5x3 format with Golden Coins, Diamonds, Stars, and Jackpot symbols feeding the Hold and Win round. The 95.85% RTP and Low/Medium volatility frame a collector game where each new symbol can preserve the feature by resetting its remaining chances.

How It Plays

Ordinary combinations pay from left to right across defined lines, with the Wild Symbol substituting for regular paying symbols. Special symbols provide the route into the main collector round.

The central decision is whether to continue through regular spins or use Bonus Buy where available. Both routes lead to the same Hold and Win board rather than separate feature types.

Theme & Atmosphere

Gems and Lucky iconography give the game a polished prize-display identity. Diamonds are functional symbols as well as decoration because they absorb the cash values already present.

The 777 subject keeps the base presentation close to traditional casino imagery. Coins and fixed prize labels make the bonus state readable without changing the visual vocabulary.

Features & Win Potential

Hold and Win locks each Golden Coin, Diamond, Star, or Jackpot symbol that lands. A new symbol resets the remaining chances, so an unfinished board can continue growing.

Fixed Jackpots are represented by dedicated symbols, while the Cash Collector role belongs to Diamonds. The Wild Symbol remains a base-game substitute rather than part of the locked-symbol payout.

Bonus & Free Spins

Hold and Win opens with three chances. Every qualifying symbol locks into place and resets that count, while the round ends when no chances remain or the board fills.

Bonus Buy provides immediate entry where the option is available. Filling all fifteen positions ends the round with the Grand Jackpot instead of waiting for the remaining chances.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (Medium-Low). The model is calibrated so the average return equals this slot's published RTP (95.85%), with wins capped at its top multiplier (5,585×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
