How the Game Plays

3 Energy Diamonds: Hold & Win by Octoplay blends the nostalgia of classic fruit machines with a high-voltage neon aesthetic. The 5x3 grid features familiar symbols such as cherries, lemons, and grapes, alongside premium icons like horseshoes, golden bells, and lucky sevens. Winning combinations are formed by landing matching symbols across the five fixed paylines, with the lucky seven symbol uniquely awarding payouts for as few as two appearances. The gameplay is accompanied by a pulsing soundtrack and vibrant visual effects that intensify when special coins land on the reels.

Hold & Win Feature Explained

The main attraction is the Hold & Win bonus, which triggers when six or more coin symbols appear in a single spin. Alternatively, landing a special energy coin can also charge the diamonds above the reels for a chance to activate the round. The feature starts with three free spins on a special grid where only cash coins, jackpots, and special energy diamonds can land. Every new symbol that appears locks in place and resets the spin counter to three. The round concludes when all positions are filled or the spins run out, awarding the total accumulated value of all locked prizes.

Energy Diamonds and Jackpots Explained

Three rotating diamonds—Increase, Collect, and Expand—sit above the grid, each providing a unique modifier during the bonus round. The Increase diamond adds its own value to every locked coin, the Collect diamond gathers the current total of all visible prizes, and the Expand diamond can add up to two extra rows, transforming the layout into a 5x5 grid. The game also features a progressive jackpot system with five tiers: Mini, Minor, Major, Mega, and Grand. These jackpots increase in value during the base game whenever jackpot coins land, and they can be triggered during the bonus round for wins up to 5,000x.
