Tetrahue: Colour Block Puzzle

Tetrahue is a falling-block puzzle game whose twist is a rotating target colour you clear by grouping connected blocks. There is no time limit, no level cap, and no mid-game paywalls, just a single endless mode that you can play entirely offline.

Shapes descend from the top of the grid. There are two ways to clear them:

• Fill a complete row in any colours.
• Group six or more connected cells of the active target colour into a single region.

The target colour rotates between Cyan, Magenta, and Yellow. When a region clears, gravity drops every remaining group as a connected unit, which frequently triggers a chain reaction. Reading the board and setting up cascades is the core of the game.

DAILY CHALLENGE
A new seeded grid every day, with a rotating daily twist (for example, Double Cascade). Everyone plays the same board that day. Available to all players.

MODES AND FEATURES
• Endless mode: speed increases the longer you play; no timer, no level cap.
• Daily Challenge: a fresh seeded board and twist each day.
• Mirror Mode: left and right controls are flipped for an added challenge.
• Prism Mode: blend colour droplets to create and clear the target shade, a colour-mixing twist on the core game.
• Colour-blind support: Block Patterns overlay a distinct shape on each colour, including every Prism shade.
• iCloud Save: your progress and unlock follow you across devices on the same Apple ID.
• Offline play: the full game runs without a network connection.
