How to Play Makaro
The grid is divided into
rooms
separated by bold borders. Each room has 2–5 cells.
A room with N cells must contain each number
1 through N exactly once
.
An
arrow
on a cell points to the neighbor (among its 4 orthogonal neighbors) with the
largest
number.
Two edge-adjacent cells in
different rooms
cannot contain the same number.
Click a cell to select it, then type a number (1–5) or tap the number pad.
Use
Check
to highlight errors,
Hint
to reveal a correct cell, and
Undo/Redo
to navigate.
Got it!
