hello@krapton.comFrequently asked
How do I play?
Tap an arrow and it slides off the board in the direction it points, but only if no other arrow is in its way. Clear every arrow to finish the level. If you tap an arrow that is blocked, it bumps and you lose a heart.
Is every level possible?
Yes. Every one of the 800 levels is checked by a solver before it ships, and clearing arrows never makes another arrow stuck. There are no dead ends: mistakes only cost hearts.
I am stuck. What can I do?
Tap the lightbulb to use a hint: it lights up an arrow that is free to go. You can also zoom in on big boards, and tap the grid button to show or hide the dots.
What happens when I run out of hearts?
You can watch a short ad for one more heart and keep going on the same board (once per try), or start the level again.
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.
How are stars counted?
One star for every heart you have left when you clear a level. Clear it without a single mistake for all three. Your best stars and fastest time are kept for every level.
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.
How do I change the colours?
Open Settings, then Appearance. Pick any theme colour, light or dark mode, and colourful or classic arrows.
