Lucky Drums 88 pays homage to ancient treasures on a 5x5 grid, where matching seven or more symbols anywhere on the reels forms an instant win. Silver and gold coins land and are collected by their matching drum above the grid, with a chance to trigger the Hold & Spin bonus game, award an instant cash prize, or apply a multiplier that boosts all wins on that spin. Gold or silver coins can each trigger their own Hold & Spin round on a matching 5x3 grid, and landing both together activates them side by side, carrying over any coins collected during the base game before an initial set of respins begins. If only one grid is active, drum symbols can randomly bring the second grid into play, and every new coin or drum that lands resets the respin count to keep the feature alive. Coins with a cash value stay on the grid for the rest of the feature, while multiplier coins clear after their next spin. When the feature ends, every coin value on the grid is added together and paid out, with a bonus applied if a grid fills completely. With its ancient drum theme and dual Hold & Spin grids, Lucky Drums 88 keeps the treasure hunt going strong.
