Tap and it fills in
Tap an empty slot and it fills right in, snug as can be.
One board · a light in every empty slot
Every empty slot shines a thin light out to the edge of the board. A slot with a light running through it has to wait. Fill the slot that light comes from first. Its light goes out, and the way is clear.
The goal, plain and simple
Fill every slot. Watch the light.
The board is full of empty slots. Each empty slot shines a thin light out to the edge of the board, with little pulses running along it like lightning bugs on a summer evening. A slot with a light running through it has to wait, so the order matters. Fill every slot and you're done.


How it works
No timers and no rush. Everything you need to see is right there on the board.
Tap an empty slot and it fills right in, snug as can be.
Tap a slot with a light running through it and you'll see Not yet. The light turns red up to that slot so you can see why. On Small that's free. On Medium and Large it costs one of your five tries.
Fill the slot a light comes from and that light goes out, so every slot it was crossing is free.

Every board can be finished, and there's always at least one slot that's safe to fill.
The lamp
Tap the lamp in the corner and, for a moment, every slot that has to wait lights up. The ones left dark are safe to fill right now. Then it fades. It costs a try, so it's there for when you're good and stuck.

Three sizes and a daily board
Every board is packed edge to edge with long, winding slots. A bigger size just packs in more of them.
