Overlapi
Read full descriptionHide full description
How much of the overlap can you keep? Overlapi is a deceptively simple game of timing and precision. Watch the moving square and tap at just the right moment. Only the overlapping area survives—and becomes the target for whatever comes next. Every imperfect tap leaves you with less room for error. Keep at least 50% to complete a level. Reach 75% for two stars, 90% for all three, or preserve everything for a perfect 100%. Take on 100 levels across 10 increasingly demanding zones. Squares become faster, arrive in greater numbers and introduce diagonal movement as you progress. Return to a level and your previous best remains visible as a target. Beat it by the smallest margin, chase three stars or keep pushing until the level is marked perfect. Earn stars to unlock every zone through play. Optional one-time in-app purchases let you unlock later zones sooner. FEATURES • Simple one-touch gameplay • 100 levels across 10 zones • Horizontal, vertical and diagonal movement • Up to 300 stars to collect • A visible previous-best target • Perfect-level and perfect-zone challenges • Game Center leaderboards and achievements • Optional one-time zone unlocks • No advertising or account required • Free to download and play Can you collect all 300 stars? Can you perfect an entire zone? The ultimate challenge is a flawless 10,000-point score: 100% on every level. Time your tap. Keep the overlap.
