Slidehue: Sliding Block Puzzle

Slidehue is a sliding block puzzle about doors. Coloured blocks sit on a small board, and coloured doors are set into its frame. Swipe a block and it slides until something stops it - another block, a wall, or the frame. It never stops half way. When it reaches a door of its own colour that is wide enough for it, it slides straight out. That one rule is the whole puzzle. You cannot park a block where you like, so the other blocks are what you steer with - and a two-wide block needs a two-wide door lined up with it. Par comes from a breadth-first search over block positions, run before the pack ever ships, so every board is known to be solvable and the grading works in airplane mode. • DAILY - the same board for everyone, once a day. Keep your streak, share your result without spoiling it. • LEVELS - 1110 boards in three chapters, from four-block openers to crowded boards with walls. • WEEKLY - five boards, new every Monday, and a medal for each. Made to respect your time: • No lives, no forced timers, no forced videos. • Gold, silver or bronze on every board, by how close you came to par. • Hints that show which block to slide and which way. • Colour-blind shapes, high contrast and a choice of palettes. • Dark mode.
