Susu & Koko is a vibrant online slot from Pragmatic Play that takes players on a sugary adventure. The game features a colorful and whimsical atmosphere filled with delicious pastries, candies and other sweet treats.
The core gameplay revolves around a 6×5 reel layout with a cluster pays mechanic. Instead of paylines, winning combinations are formed by landing groups of five or more identical symbols anywhere on the adjacent reels. After a win, the winning symbols disappear, triggering a Tumble feature. New symbols fall from the top to fill the empty spaces, creating opportunities for consecutive wins and potentially larger payouts.
Adding to the excitement are the heart-shaped multiplier symbols. These appear randomly on the reels during both the base game and Free Spins and have random multiplier values between 2x and 500x. When a Multiplier symbol is part of a winning cluster, its value is applied to the entire win, resulting in potentially significant boosts.
The key to unlocking the Free Spins bonus is the Scatter symbol, which looks like a delicious pizza. Landing 4 or more Scatters anywhere on the reels triggers 10 Free Spins. During the free spins, a special feature comes into play. Part of the reels are initially blocked by locked positions. With each winning tumble sequence, one of these locked positions is unlocked, expanding the playable area and increasing the chances of even bigger wins. This continues until all reel positions are unlocked.
An optional ante bet feature allows players to increase their bets and potentially benefit from a slightly higher return to player (RTP) rate. In addition, for those seeking more immediate access to the bonus round, a Buy Free Spins option is available at a cost of 100 times the current total bet.
