Play 3 Energy Diamonds: Hold and Win Slot by Penguin King for Free

3 Energy Diamonds: Hold and Win by Penguin King is a high-variance 5x3 slot where the Hold and Win feature is charged by three special diamond types: a Sweep Diamond grabs all active coin values at once, an Increase Diamond boosts every coin on the grid, and an Expand Diamond stretches symbols into adjacent positions. Five jackpot levels cap the feature, with the Grand award at 5,000x needing a full grid of locked symbols. Top prize is 5,200x.
