0h h1
Fill the grid with red and blue: no three in a row, equal counts per line, no two lines alike.
0h n0
0h h1's companion: every blue number counts exactly the blue dots it can see.
Lamp Code
Read the lighthouse keeper's signal before the lamps go dark. Guess the five-letter word in six tries, with gold and amber lamp feedback that also speaks in shapes for colour-blind play. Then switch to Beacon and crack a four-lamp colour code instead.
Star Chart
Restore a monastery's faded star-chart by setting glyphs so every row, every column and every 3x3 ward holds all nine marks exactly once. Four graded difficulties, a fresh daily chart, pencil marks, undo and a hint — made to be played equally well by thumb or by keyboard.
