Cubewords

Cubewords takes a clued crossword and folds it around a cube. You drag to turn the cube, tap a square and type, and the clue for the selected answer sits under the cube with the letters you have so far. Words cross the edges and carry on along the next face, so a letter you fill on one side helps with a clue on the other.

The page opens on the day's Mini, a 2x2x2 cube with six clues that takes a minute or two. From the menu you can move on to the Easy 3x3x3 cube, also free, and the Hard 4x4x4 cube, which needs Plus. On the first Sunday of each month a much larger mega cube appears. A timer runs while you solve, a lightbulb gives hints, and the menu counts your streak and cubes solved.

Beside the crosswords there is Wordwind, a daily word find in which you connect letters on a small cube. The game also has many looks for the cube, from paper to neon and glass, and an animation that takes the cube apart when you finish. Making your own cube for a friend is free. Cubewords Plus costs $3.99 a month or a yearly price and opens the Hard and mega cubes, the archive of past days and every look. There are apps for iPhone and Android as well.
