Monster Sweeper
Read full descriptionHide full description
Monster Sweeper is a dungeon-crawler twist on the classic hidden-cell puzzle formula. Explore a grid-based dungeon where every tap matters. Instead of mines, the board hides monsters, artifacts, and deadly poison traps. The numbers on revealed cells show the total strength of adjacent monsters, so success depends on deduction, risk management, and smart combat choices rather than luck alone. Fight your way through the dungeon, collect loot, level up your hero, and prepare for a final boss battle. Regular enemies resolve automatically, while boss encounters add a tactical layer where you choose where to attack and where to block. Features: ⢠A fresh blend of puzzle deduction and RPG progression ⢠Numbers that show adjacent monster strength, not just enemy count ⢠10 monster tiers, from rats to infernal creatures ⢠Artifacts that heal, boost stats, reveal danger, or expose weak enemies ⢠Level-ups with meaningful choices between health and attack ⢠Chain reveals and dynamic board updates as enemies are defeated ⢠Tactical boss combat with attack and block targeting ⢠Three difficulty levels ⢠Achievements and leaderboards Easy mode is available for everyone. Unlock the full game to access Normal and Hard difficulties, achievements, and leaderboards.

The pictures look the same, but something has changed. Compare two charming scenes and look closely. A color may be different, an object may be missing, or a shape may have quietly changed. That quick spark when you find it is the heart of the game. Spot Diff is an observation puzzle with 204 stages of illustrated picture pairs. ā 204 case files Travel through coastlines, deep sea, night skies, space, mountains, polar lands, forests, gardens, workshops, city festivals, desert ruins, laboratories, and storybook worlds. Compare the pictures and discover differences in a variety of settings. ā A challenge every tenth stage Stages 10, 20, 30, and every tenth stage after them hide more differences and tougher changes. Every twentieth stage closes a chapter and awards double challenge coins. ā Combos and three-star clears Find differences in a row to raise your score multiplier. Wrong taps cost time, while fast clears with fewer hints earn more stars. ā Daily missions Take on three daily missions, such as playing stages, finding differences, and earning stars. Complete them all for an extra reward, then spend your coins on helpful tools. ā Detective tools Use the magnifier to reveal a missed clue, add 30 seconds with the pocket watch, or instantly solve one clue with Auto-Find. ā Start quickly and keep playing The first chapter is included with the app. Later stages download quietly as you progress, so the next case is ready when you are. No account or sign-in is required. Install the game and begin your first case.
