Tetrahue: Colour Block Puzzle

New: Prism Mode. Blend colour droplets to match the target shade, a premium colour-mixing twist. Plus the Daily Challenge and endless mode. No timer. Play offline.

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.
