SlingShot Merge

Read full description

Sling, merge and duel real players in real time. SlingShot Merge is a physics puzzle: pull back the slingshot and launch numbered balls onto the board. Matching numbers merge and grow — and 4 or more matching balls merge in one go. This is not a grid-slide puzzle: every shot is aimed, and physics decides where the balls land. NEW: ADVENTURE 90 handcrafted levels across 6 worlds — Beginnings, Ice Land, Stone Forest, Ocean, Volcano and Galaxy — each with its own landscape. Reach each level's goal, earn up to 3 stars and master portals, planets, ice, cages, treasure chests and timer balls. Finish a world to open its reward: coins, lives and new ball sets. THREE WAYS TO PLAY · Classic — aim every shot and keep the balls below the red line. · Vortex — balls flow toward the center and merge in a swirling vortex. Keep them inside the gold ring. · Adventure — level by level, world by world. LIVE 1v1 DUELS Get matched with a real opponent in seconds. Three minutes, highest score wins — overflow the line and you lose instantly. PLAY A FRIEND Create a private room, share the code and duel someone you know. WEEKLY SEASONS Every Monday a new season starts. Climb the trophy, score and vortex leaderboards and earn coin rewards. MAKE IT YOURS · 15 ball sets — donuts, footballs, planets, cat and dog breeds and more · 12 live themes with animated backgrounds, themed slingshots and effects · 60 hand-drawn avatars and your own player name · Permanent power-up upgrades for undo, hammer and bomb EVERY DAY · 6 daily missions with a completion bonus · Daily reward streak · A new 30% deal in the store every day YOUR PROGRESS FOLLOWS YOU Score, coins, trophies, Adventure progress and unlocks are saved with your Game Center account.
