Drag a bug onto the board. Rays run from its arms to the edge of the grid, and every cell a ray touches lights up. Light all of them to solve the board. Boards change with different mechanics: walls that stop a ray, gaps rays cross without lighting, cells that must never be touched at all, repels that clear the ray that hit them, traps that reset everything, and relays that fire rays of their own once they light. Every generated level has one solution and can be reasoned out from the information you have on the screen. No guessing, no timers, no lives, and nothing runs while you are looking at it. Worlds 16 worlds and 346 levels, graded from a two-piece opener to boards that use every element at once. Each world introduces one idea and then makes you use it: corners, corridors, blots, long reach, diagonals, crosstalk. Daily One board a day, the same board for everyone who plays it. A calendar of every day you have solved, and a streak that carries free solves with it. Endless Boards generated on the device by grade, for as long as you keep clearing them. Beat all the levels already? Play for as long as you like, at whatever difficulty feels best! Classic All 128 levels of the 2014 original, rebuilt in the new engine. These frequently require you to visualize a solution and place specific pieces last. Stuck A solve places one correct piece for you and locks it there. You earn them from daily streaks, from finishing a world, and from Classic milestones. On a board you have already beaten, solves are free. Offline and yours No account, no sign-in, no server. Progress lives on the device and can be erased from the settings screen. Plays even with the network off. The game is in English, French, German, Italian, Spanish, Brazilian Portuguese, Russian, Turkish, Arabic, Hebrew, Japanese, Korean and both Chinese scripts. ## Key features - Infect cells with bugs - Use walls and repels - Hundreds of hand-built levels - Daily puzzles - Endless mode - Offline play ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Remove Ads | $4.99 | one-time | ## Is Grid Infect safe?

Rate the game from Settings. ### 1.0.2 — 2026-10-22 • Endless: BEST now records the most levels you clear in one run. A reset or a trap no longer cuts it short, and your current best carries over. • Tan skin: the core dots, the SOLVE badge and the board markings are darker and easier to see. • The SOLVE badge is easier to read on every skin. ### 1.0.1 — 2026-10-16 • Fixed a rare case on the original 2014 levels where using SOLVE several times in a row could use up your SOLVEs and still leave the board unfinished. SOLVE now only places a piece if the level can still be completed. • When you're out of SOLVEs, the button now reads "+1 SOLVE (AD)" so you know a short ad will play before you get one. • Rays now draw cleanly along diagonals when you place a piece. • Cells now light up from their center outward. ### 1.0 — 2026-10-15 No release notes. ## Apps similar to Grid Infect | App | Rating | Price | Category | | --- | --- | --- | --- | | [Crunchyroll: inbento](https://appshunter.io/ios/app/crunchyroll-inbento/id6457262278) | 4.6 (72) | Free | Games | | [Moonlit Town: Merge & Story](https://appshunter.io/ios/app/moonlit-town-merge-and-story/id6759944119) | 4.4 (37) | Free | Games | | [Slope Run Game](https://appshunter.io/ios/app/slope-run-game/id1472706327) | 4.7 (17,254) | Free | Games | | [Animal Land: Island Farm](https://appshunter.io/ios/app/animal-land-island-farm/id6745165798) | 4.7 (802) | Free | Games | | [Dream Detective: Merge Game](https://appshunter.io/ios/app/dream-detective-merge-game/id6448940301) | 4.3 (134) | Free | Games | | [Red Hands - Fun 2 Player Games](https://appshunter.io/ios/app/red-hands-fun-2-player-games/id966897134) | 4.6 (8,101) | Free | Games | ## Related topics [infect them all](https://appshunter.io/ios/topics/infect-them-all) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
