## What is Blub?

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.
