Tally (Mind Loft)

Tally is a number puzzle on Mind Loft, a free site of daily browser games, in the sudoku family with a ledger twist. Each day gives a grid with a target printed at the end of every row and column, and a rack of number tiles. You place every tile so that each line adds up to its target.

What sets it apart from kakuro or a magic square is the supply. The rack holds exactly the tiles the grid needs, no more and no fewer, so when the arithmetic alone leaves two ways to finish a line, counting what is still on the rack decides it. Every board has a single solution.

A few squares start filled and a few are blacked out. The header counts your moves against the fewest possible (14 on 29 October 2026) and how many of the ten lines balance. Each target also shows what its line still needs, such as 6 in 2. Digits repeat, so the rack shows how many of each you hold and strikes out the ones you have none of. You tap a tile and then a square, or drag a placed tile to move it. Sending a tile home is free, and a Hint button and an Undo sit under the rack. Solving in the fewest moves is the perfect score, and ties break on fewer errors and then time.

A new ledger goes up at midnight US Eastern Time, and the Sunday Edition is a bigger 6x6 board. Mind Loft suggests Crux, Span and Dating alongside it; for more sums, its Sums (kakuro) and Carve are close relatives.
