How the Game Plays

Gems Up is a vibrant, gem-centric slot from Konami that utilizes a standard 5x3 grid with 30 fixed paylines. The aesthetic is built around high-value jewels and classic slot symbols, brought to life through the provider's signature Action Stacked Symbols mechanic. This feature ensures that a portion of the reel positions is replaced with a randomly selected symbol before each spin, increasing the potential for full-screen wins. Winning combinations are formed by landing matching symbols from left to right, while the inclusion of a forced Extra Bet activates the game's more lucrative secondary features.

Free Spins Explained

Triggered by landing three Sign scatter symbols on the middle reels, the free games round initially awards five spins. The feature is unique because it starts at the "Blue Level," where lower-paying symbols are replaced with gem symbols that carry instant credit prizes. Retriggering the bonus by landing two or more scatters adds additional spins and upgrades the feature to the "Red Level," which converts more symbols into prizes. A second retrigger reaches the "Gold Level," where the vast majority of the symbols on the reels become credit-bearing gems.

Prize Fever Feature Explained

Outside of the free spins, the Prize Fever feature can trigger randomly during any base game spin. When active, one of three symbol groups—Blue (poker ranks), Red (mid-tier gems), or Gold (high-tier symbols)—will transform into gems containing specific credit values. If any of these symbols land on the grid, their values are totaled and awarded instantly. This feature also serves as the gateway to the game's jackpots; filling four or five columns with credit gems of the same color awards the Gems Jackpot or the Fine Gems Jackpot, respectively.
