Dotivo: One Line Puzzle

One line. Every cell. No shortcuts.

Drag from the ring and fill every cell of the shape in a single unbroken
line, finishing on the goal. You will understand it in three seconds. The
later boards will take you considerably longer.

200 HAND-CUT LEVELS
Ten chapters, from nine-cell warmups to eighty-cell shapes that need real
planning. Every board is a different silhouette - no two levels in the game
use the same one.

RULES THAT ARRIVE WHEN YOU NEED THEM
Arrows that can only be left one way. Numbered checkpoints that must be
crossed in order. Holes punched inside the shape. Each is taught on the level
that first uses it, with a board that solves itself, and the clock waits until
you are ready.

BUILT TO BE QUIET
Off-white paper, dark ink, one accent colour at a time. No flashing banners,
no countdown pressure, no character shouting at you. The board fills the
screen because the board is the point.

FAIR WHEN YOU GET IT WRONG
Blocked moves are refused for free with a nudge. Only stranding part of the
board costs a heart, and it rewinds you to the last place you had a real
choice. Three hearts on every level, start to finish - the difficulty is in
the boards, not in taking your lives away.

PLAYS ANYWHERE
Fully offline. No account, no sign-up, no email. Your progress saves to your
device and syncs to the cloud when you have signal.

Dotivo is free to play. It shows ads between levels and offers optional
videos you can watch to double a reward or keep going after a loss. A
subscription removes ads entirely and gives you unlimited hints, and coins can
be bought outright if you would rather not subscribe. Neither is needed to
finish the game.
