Rank Up: a series by ThePedallingPianist and bellal exploring the full rank constraint within 5x5 grids... SEE ALL PUZZLES



Chaos Construction: Within the main grid (inside the thick border), find five non-overlapping 5-cell regions and fill every cell with a digit from 1-5 such that digits do not repeat in a row, column or region.

Modified Full Rank: A value in an external cell represents the rank of the number formed by reading the digits in that row or column from that direction, STOPPING at the first region border, where (1) is the lowest such row or column and (20) is the highest. For example, if a row reads "14|523", then the clue to the left of the row shows the rank of the number "14", and the clue to the right of the row shows the rank of the number "325". "X" may refer to any number from 1-20.

Modified Tied Ranks: If two ranks are tied, the value in both external cells is the lower of the two ranks being shared, AND in this puzzle, unlike the others in this puzzle series, an equals sign will appear after a tied rank. For example, if the lowest four ranks are "2", "14", "14" and "52", the values in the relevant external cells would be (1), (2=), (2=) and (4) respectively.
