Easy to use game, nice to have a new challenge each week that doesn’t cost extra money🥳👍👏

Excellent puzzle app

I love this app. It is easy to use, and the many difficulty levels mean I can choose how much brain-power I want to use. No ads, no ‘challenges’, no distractions. Just a clean, well thought out game with intuitive controls. Free starter packs are great, and the free weekly puzzles make it possible to play for free for a long time. If you play a lot, you can buy packs of the level and size you want.

Tolle Spiele

Es ist fordernd, aber nicht zu schwer. Es macht Spaß.

Love it

Just started to learn how to do the very basic level, the app makes it easier to pencil in the numbers in the squares which helps to visualise the missing mumbers
