Tetrahue: Colour Block Puzzle

Tetrahue is a colour puzzle game where falling blocks descend onto a grid. Clear the target colour to trigger cascades. Premium Prism Mode adds a colour-mixing twist: blend droplets to create the target shade. A HUD chip shows how many points separate you from your personal best while you play. Two ways to clear: • 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 piece group as a connected unit, which frequently triggers a chain reaction. There is no level cap, no time pressure, and no mid-game paywalls. DAILY CHALLENGE A new seeded board every day with a rotating twist: Double Cascade, No Hold, T-pieces Only, Mirror Controls, Single Colour Day, and Prism Day. Everyone plays the same board that day. Available to all players, no Premium required. Share your score with friends when you finish. MODES • Endless: the default mode, no timer, no level cap, speed builds the longer you play. • Prism Mode (Premium): a colour-mixing twist. Blend droplets to create the target shade; the target now spans six colours instead of three. A short in-game tutorial introduces the mechanic. • Mirror Mode (Premium): left and right controls are flipped, for an added challenge. CONTROLS Drag to slide, tap to rotate, swipe up to hold the active piece. ACCESSIBILITY Block Patterns overlay a distinct shape on each colour, including every Prism shade. Toggle in Settings.
