Teil wählen, drehen → aufs Brett klicken (Ziehen geht auch). Jede Zeile und Spalte auf 15 bringen.
The board is generated so every row and column already sums to 15, then cut into tetrominoes — so a solution always exists. Numbers may repeat and no 1–9-per-box rule applies. Boards grow larger over the set, and 50 puzzles refresh each month.
