Tap (or click) two numbers to link them. A pair is valid when the two numbers
are equal or add up to 10, and the path between them is clear — horizontally,
vertically, diagonally, or wrapping from the end of a line to the start of the
next one.
Clear every number on the board to win the stage. Fill a whole row and it
disappears. If no moves are left, press ADD to copy the remaining numbers to
the end of the board, or use a HINT to reveal a pair.
Controls: mouse click or touch only — no keyboard required.
