Spin the digits, find the fits.
Drag, rotate and reason your way through 250 boards — some solved in a minute, some worth sitting with.
DigiSpin's ten pieces are shaped like the digits 0 to 9, built from bars that sit on the lines between cells, the way a seven-segment display works. Place all ten on the board, rotating each one to fit, so that no two pieces ever overlap.
Every board below is drawn at load time by a small script that reimplements the app's own digit shapes, rotation, slot math and bar geometry — so a clash, a legal pairing, a dimmed given piece and a full solution all render the same way the real app draws them.
Place all ten digit pieces, 0 to 9, on the board so that no two of their bars occupy the same spot. Every piece can be rotated to help it fit.
The pieces sit on the lines between the board's cells. Each digit is a shape made of short bars, the same shape as a seven-segment display: 0 is the four edges of one cell, 1 is a straight line with no width, and 2 to 9 each span two cells.
A clash is two pieces trying to use the same bar position on the board. DigiSpin won't allow it: the move is refused, the shared bar turns solid red, and a message names the other piece already using it.
The app's own first-time tutorial teaches this with a 7 and a 1: an upright 7 and a 1 dropped flat across it share two bars and get refused the same way.
Drag a piece from the tray to place it on the board, or drag a piece already on the board to move it. Tap a piece in the tray to turn it a quarter turn before you place it.
Some pieces may already be placed and locked for you, giving you a head start — the rest is up to you to work out.
Stuck? Hint places one remaining piece exactly where the solution has it, and locks it there. It costs one of a limited number of hints, shown next to the button.
Some levels have more than one valid layout — finding a different one than before still counts. To see every solution you've found for a level, go to the Levels screen and hold down on it.
The 8, 9, 1 and 3 are locked in place from the same solved board shown above. Tap a tray piece to pick it up, tap it again to rotate it, then tap a board cell to drop it there — place all six to solve it.
Every board has at least one solution. Finding all of them is up to you.
DigiSpin is built for iPhone and iPad, with a theme that follows your device's light or dark setting and a choice of colour-blind-friendly digit palettes. It runs entirely on your device: no accounts, no network calls, no analytics. Progress, stats and settings stay local until you delete the app.
