History of the puzzle[edit]

First appeared on WPC 2016/Round 11, an "innovative" round. The author of the puzzle was Matej Uher (Slovakia).

A similar puzzle with all cells being occupied with numbers and the word being "ABCD" can be seen on Naoki Inaba's (Japan) website under the name アンイーブン ("Uneven"). [1]
