Sudoku Puzzle —
classic 9×9 Sudoku plus the Kropki variant, where dot markers between cells tell you whether
the neighbouring digits are consecutive or in a 1:2 ratio.
Play the full version as a
Sudoku game in your browser,
with a new grid published every day.
24 Points Game —
four numbers on the board, combine them with + − × ÷ so every hand totals exactly 24.
Short rounds, no timer, good for warming up mental arithmetic.
