Tetra: Blocks & Flow

Make a little room for your next move.

Tetra is a block puzzle for iPhone. Place colorful pieces on an eight-by-eight board and complete rows or columns to clear them. Take your time, plan a satisfying combo, and find your own rhythm.

THREE WAYS TO PLAY

Arcade — Keep the board open and beat your best score. Build consecutive clears into streaks, clear several lines together, and use one rescue per round when you need a second chance.

Challenge — A new puzzle arrives each day. Complete six puzzles in a week to reveal an illustrated animal and add it to your Trophy Case. Catch up on missed days before the week ends, with 52 animal portraits to discover.

Flow — Settle into an endless puzzle with no score, timer, or game over. Reveal a whale, deer, and owl among the stars while an acoustic piano soundtrack responds to your play. When the board fills, it gently renews and your constellation progress continues.
