hello@krapton.comFrequently asked
How do I play?
Drag across empty cells to draw a rectangle. Each rectangle must hold exactly one number and cover exactly that many cells. When it is right, it turns into a cat. Cover the whole board with cats to finish the level.
Do I have to start dragging on the number?
No. Start on any empty cell. Numbers can sit anywhere inside their block, so you can drag from any corner. A selection can never cover a cat that is already placed.
Is every level possible?
Yes. Each of the 1,000 levels is checked by a solver before it ships and has exactly one solution, so there is never any guessing.
I am stuck. What can I do?
Tap the lightbulb to use a hint: a cat moves into place for you. You start with three hints and earn another every 10 levels you clear. With none left, you can watch a short video for one. You can also tap a cat to take it back.
What happens when I run out of hearts?
You can watch a short video for three more hearts and keep the same board (up to twice per try), or restart the level.
Does it work offline?
Yes. Every level is inside the app and your progress is saved on your phone. You only need a connection for ads.
What happens after the last level?
When you finish all 1,000 levels, you get a celebration and the choice to start over from level 1. Your hints and settings stay.
Will I lose my progress if I change phones?
Progress is stored on the device, so it does not move to a new phone, and uninstalling the app removes it.
Can I turn off the sounds or vibration?
Yes. Open Settings and tap Sound or Vibration. You can also hide the numbers on placed cats with Block count.
