Logic Masters Deutschland e.V.

Divide the grid into five orthogonally connected regions containing five cells such that each region contain the digits 1 through 5.

Digits may not repeat along each rows and columns.

Consecutive digits on an orange Dutch Whisper line must differ by at least 2.

Additionally, consecutive digits on a Dutch Whisper line are from different regions. For example R2C1 and R3C1 are connected by a Dutch Whisper line, therefore R2C1 and R3C1 belong in different regions.
