Huedle

A shuffled grid of colours that has to be sorted back into a smooth gradient. Two opposite corners are welded in place and define the two ends of the ramp; everything between them is scrambled and has to be swapped back into order. There is nothing to guess and no way to lose, which turns the whole thing into a race: how few swaps, and how fast.

1. Start the board. The clock and the move counter begin the moment you do.
2. Swap tiles by dragging one onto another, or by tapping one then tapping its destination. A tap on the same tile again deselects it.

Huedle is the colour game for people who would rather sort than guess. There is no hidden answer, no attempt limit and nothing to get wrong, only a scrambled ramp and the question of how efficiently you can rebuild it, which makes it unusually low-stress for a daily. The dots that confirm each correct tile turn what could be a frustrating eyeball exercise into steady, visible progress. The daily leaderboard gives it teeth, because it ranks moves as well as time and rewards thinking over frantic swapping. It is free, carries no advertising, needs no account, and there is a full dated archive if one board a day is not enough. It is still labelled beta, and the developer says as much: scores and leaderboards may be reset while the game is in development.

Per-tile and immediate. Every correct placement is confirmed with a pulse, a sound and a dot that stays there, so you always know exactly how much of the grid is settled. Above the board, a completion percentage, a move counter and a running clock update live. Nothing tells you a swap was wrong; it simply does not get a dot.

Today's puzzle

The daily board, stamped with its date, its number and a difficulty label. The grid size changes with the difficulty, so an Easy day can be 4x5 while a Hard one runs 6x7.

Archive

A month-by-month calendar of every board since launch. Each day shows its difficulty and dimensions up front, and marks whether you started or completed it.

Leaderboards

Each day's board has its own table, with columns for time, moves and a combined score, and tabs to sort by any of the three.

• Work outwards from the locked corners, which is the game's own advice. The edges only have to blend between two known colours, so they are the easiest lines to read; the middle becomes obvious once the borders are right.
• Every swap moves two tiles, so aim each one at a pair that both belong where they are going. Blind shuffling inflates the move count fast, and moves are weighted heavily in the score: the leaderboard regularly puts a slower run with fewer moves above a quicker, sloppier one.
• Trust the dots over your eyes on the diagonals. A gradient across a rectangle changes in two directions at once, and the tiles in the middle of the grid are the ones where hue and lightness both shift, which is exactly where eyeballing goes wrong.
