Great if it wasn’t for the cost
The game design is excellent, very conveniently laid out with useful features like the calculator, and the optional colours for clearer differentiation between groups. Wonderful that both pencil and pen are options at the same time etc. I like how you can put the numbers in in any order eg.2938 to remember the combinations for 11. However you only get 8 free puzzles, at first I thought it was a daily thing where you’d get new ones each day but no. I’ve done them now so I’m deleting the app because I’m not willing to pay for more. If you do want to pay then the app is good, otherwise it won’t last over a week
