About:
The follow-up to 0h h1 by the same author. Each numbered blue dot must see exactly that many other blue dots along its row and column, and red dots block the view. Tap to cycle a dot between red and blue; the hint button walks you through the next logical step. Boards run from 4x4 to 9x9, all generated locally.

0h h1
Fill the grid with red and blue: no three in a row, equal counts per line, no two lines alike.
Daily Puzzle
A new small logic puzzle every day, and a different kind of puzzle for each day of the week.
Tumble Block
Roll a two-cell stone reliquary end over end across broken tile mechanisms and land it standing upright on the glyph. Twelve hand-built, solver-proven boards with switches, bridges and fragile tiles, unlimited undo and a one-tap reset.
Canal Jam
A crowded canal lock is jammed solid and the copper barge is boxed in. Every narrowboat only drifts the way it points, so you slide the others aside, clear a channel, and ease the copper barge out through the gate.
