Blub - Tap the Gap

Tap the gaps, pop the colors

Free · Designed for iPad. Not verified for macOS.

Tap an empty cell, and any matching-color tiles in the four directions pop. That's the whole game. It sounds simple, and it is — for the first five seconds. Then combos start showing up, and streaks, and daily leaderboards, and real-time 1v1 duels. Sessions are short. A round of Time Attack is 60 seconds. The daily puzzle takes about a minute. A live match ends before your coffee. Modes Time Attack — a 60-second sprint. Chain combos and climb the leaderboard. Endless — tiles keep spawning. Clear matches to survive. One optional revive per run if you want it. ONE SHOT — one daily board everyone plays. Fewest taps wins. A fresh board every 24 hours. 1 vs 1 — live matchmaking. Same board, both players, whoever clears faster takes the round. A few things about blub It's built around one mechanic. Learn it in five seconds, keep finding depth for weeks. Made to be quiet. Small on the screen, low-key sound, easy on the eyes. Portrait, one-handed. Every board is solvable. Every combo is on you. No pay-to-win. Ads are opt-in only — used for reviving in Endless or topping up hearts. Nothing forced. Purchases are cosmetic. Themes, share-card styles. Nothing that changes the game. See you on the daily leaderboard.
