About this game

Someone picks a number. You have to find it. That part is easy — so every challenge takes something away.

Mines sit on the numbers a careful player would try next. A few numbers are shown to you for six seconds and then forbidden. Your own guesses get masked, so the search has to stay in your head. And in some challenges the board lies about what you played.

Six complete challenges are free: Classic, Recall, Timed, Unreliable, Minefield and Scavenger. One permanent £2.99 purchase unlocks the other twenty-six and Challenge Designer.

Train and Play. Train challenges keep fixed rules, so your results mean the same thing every time and you can watch them move. Play challenges trade that for more chaos and more replay.

Design your own. Every rule the built-in challenges use is a control you can set: the range, the budget, the clock, the mines, the lies. The app shows you the worst case as you build, and refuses to save a challenge that cannot be won. The full challenge collection and Challenge Designer are available together as one optional, permanent purchase. There is no subscription.

No in-app account and no ads. Challenges and progress stay on your phone, and play works offline.

What’s new
