Pair equal numbers or two that make 10. Clear the grid, no luck involved.
Read full description
A card full of digits. Tap two that are equal (4 and 4) or that make 10 (3 and 7) and can see each other in a straight line: across, down or diagonally, with only empty cells between. Both are crossed out. When a row or column is empty, it disappears and the grid closes in, so new neighbours meet. Clear the whole card to win.
EVERY BOARD CAN BE CLEARED
Each level is built backwards and checked by a solver: there is always a way to clear it without adding a single number. No luck, no shuffles. The puzzle is choosing which pair to take, because the obvious one can leave a digit stranded.
THE GRID CLOSES IN
Removing a whole row or column pulls the rest together. A 4 that was out of reach slides onto the same diagonal as another 6. Plan for it and the last pairs fall into place.
PADLOCKS
A locked digit only opens once the two digits that sat to its left and right are gone. Clear around it first, or it blocks the way.
ADD A ROW WHEN YOU ARE STUCK
Add drops one new row at the bottom. Every new digit pairs with the digit above it, and Add also opens one padlock. You get three free Adds per level, but each one costs a star: clear without Add for three stars.
THREE WAYS TO PLAY
Relax: small cards that teach one rule at a time.
Hard: taller grids and more padlocks.
Expert: full sheets with many decoys, where one careless pair costs the three stars.
HELP WHEN YOU WANT IT
Undo (three free per level) takes back the last pair or the last Add. A hint shows the next pair of a clean solution. Selecting a digit lights up every partner it can take, so you never hunt for pairs, you choose them.
NO PRESSURE
No timers, no lives. Big digits on a calm paper card, playable offline.
ADS AND THE ONE PURCHASE
The game is free. After your first few wins, a short ad may play between levels, at most every third one and never in the middle of a level. Extra undos, hints and extra Adds are optional rewarded ads that you choose to watch. The one purchase, Remove Ads, switches off the ads between levels for good; the optional rewarded helps stay available.
