In all of the 8 3x3-boxes on the edge of the grid a pentomino has to be placed in the way they are presented: the pentominos must not be rotated, mirrored or moved within the 3x3-box. The sum of the digits covered by a pentomino shape is increasing with 2; If the sum of the F pentomino is 15, P=17, T=19 and so on. If F=16, P=18, T=20…
The pentominos have to be placed clockwise in increasing order. Finding out where to place the pentominos is part of the puzzle.

F hat die niedrigste, dann P, dann T usw., Z die höchste.

Hat F auf jeden Fall die niedrigste Summe? Oder ist das nur zufällig in beiden Beispielen oben so?
