How to play

Fill every cell with a number. Each number is the size of its block: a 3 lives in a block of three cells. Two blocks of the same size can't touch side by side. A short tutorial teaches this the first time you open the game, and Settings → How to play shows it again.

Place a number — pick it below the board, then tap an empty cell.
Remove a number — double tap the cell.
A move won't go in? It breaks a rule. Numino refuses moves that break a rule instead of letting you get stuck.

Hints

A hint fills in the next block for you. The free version gives you a few hints; after that, a short video gives you one more. With "Remove ads", hints are unlimited.

"Remove ads"

What it includes

A one-time purchase that removes all ads and gives unlimited hints. It is not a subscription.

Restore a purchase

New phone, or reinstalled the game? Tap Restore purchases in the shop or in Settings. Use the same Apple ID or Google account you bought it with.

Refunds

Apple and Google handle all refunds. iOS: reportaproblem.apple.com. Android: Google Play refunds.

Ads and privacy

In the EU, the UK and Switzerland you can change your ad consent at any time in Settings → Privacy choices. Details are in the Privacy Policy.

Your progress

Progress is saved on your device. It does not move to a new phone. To start over: Settings → Reset progress. This cannot be undone.
