Fillomino puzzlesMy database includes 845 puzzles for the moment and I'm constantly generating more.
Rules: Fill in the board so each number is a member of a block with the same amount. Each block is defined as cells above, under, right and left (not diagonal). Eg, there should always be two 2's beside eachother (above, under, right and left), three 3's etc. NB, there can be blocks not defined of the startnumbers.
