SOLVE MODE
Roll three dice, enter a target number, and see every way to combine your dice — using addition, subtraction, multiplication, division, exponents, and roots — to reach it. Great for checking your own work or discovering paths you hadn't thought of.
CHALLENGE MODE
Roll a set of dice and a target, then build the answer yourself — tapping dice and operators into place, left to right, with instant feedback when you're right. Six levels of difficulty take you from simple addition all the way up to exponents, fractional exponents, and roots, with targets up to 1,000.
Challenge mode includes 3 free puzzles to try. After that, it unlocks with a single one-time purchase — no subscriptions, and Family Sharing means one purchase covers your whole family.
BUILT FOR PRACTICE
Six progressively harder levels, each changing exactly one thing about the challenge
Customizable dice colors and styles
Full support for larger text sizes and VoiceOver
Solve mode stays completely free, no purchase required
