Happy Birthday by Eyecon is a 5-reel, 3-row video slot with 25 fixed paylines and a birthday-party theme. The reels use bright, cartoon-style symbols including cake, party hats, gifts, champagne, cupcakes, and balloons. The game shows an RTP of 95.4% and allows bets from 0.01 to 12.5, with line wins paid from left to right across the fixed patterns.
The cake symbol acts as a Scatter, while a separate Substitute symbol functions as Wild and can replace most symbols except the Scatter. Three or more cake scatters trigger 15 Free Games, with prizes tripled during the feature. The free games round can retrigger, up to a maximum of 15 times, making it the main bonus event described in the paytable and help screens.
