Sevens Heat 40 — A Classic with a Modern Twist
Sevens Heat 40 by Pateplay is a refreshed classic with 5x4 reels and 40 fixed paylines. The gameplay is straightforward: spins trigger a cascade of fruit symbols — cherries, lemons, sevens. Animations add flair: symbols “ignite” on winning combinations, creating a lively atmosphere.

Payouts depend on combinations: sevens are the most generous, fruits are basic. The slot suits those who enjoy simple slot machines with a modern polish. In demo mode, you can test the mechanics and visuals at your own pace.
20 Super Hot — Hot Fruits and Big Wins

Wild (red seven) substitutes for everything except scatter (star), which pays in any position. The gamble feature lets you double a combination by guessing a card’s color. It’s an ideal choice for fans of classics who appreciate straightforward gameplay. Demo mode helps you master the paylines and dynamics.
