## What is Tetra?

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.

PLAY YOUR WAY

• All three modes work offline.
• No ads, subscriptions, or paid gameplay unlocks.
• Optional Game Center leaderboard and eight achievements.
• Drag pieces, or tap a piece and then a board cell.
• VoiceOver controls, adjustable drag sensitivity, sound and haptic settings, and Reduce Motion support.
• Your current rounds and collection are saved on your iPhone.

Tetra is free. If you enjoy it, optional tips help support its development. Every mode and every animal is available without a purchase.

Game Center and tips require an internet connection. Game Center shares scores and achievements; boards and animal collections remain on your device.
