The Fillomino Frog 4
(Published on 17. June 2025, 03:35 by Die Hard)
Our friend the fillomino frog has discovered parity.
I do strongly recommend you complete this series of puzzles in order.
Rules
Fillomino. Divide the grid into regions of 1 to 9 cells, each filled with its size, such that no two regions of the same size share an edge.
Anti Row/Column. The digit N cannot appear in row N or column N.
Lotus Flowers. A digit on a lotus flower indicates how many lotus flowers contain that digit and how many regions there are of that size. No region can contain more than one lotus flower.
Frog's Path. Find a path for the frog to reach the mosquito such that:
- It always hops one cell at a time over a cell edge.
- It does not visit all 4 cells in a 2x2 area.
- It visits one cell (and only one cell) in every region.
- It always alternates between odd and even digits.
Counters. In the column on the right, record how many times each digit appears on the frog's path.
Please leave a comment if you enjoy this puzzle.
Solution code: The first 12 digits on the frog's path.

Fun extension of the series! I think adding the parity restriction makes this entry a touch easier than the previous one, but no less fun to sort out. The breakin, and the lotus flowers, were quite fun. Excited to see what Fillomino Frog encounters next. Thank you!
