## What is Solve Ten?

Solve Ten is a number puzzle without operators.

Using four numbers, you uncover the hidden operators and determine the correct order
that results in 10.
With each guess, you see whether the result is less than, equal to, or greater than 10,
along with clues indicating which numbers are correct and whether they are in the correct positions.

Using this information, you try to find the correct solution within seven attempts.

Two play styles are available:
TODAY — one puzzle per day, including the new Plus/Minus variant
ENDLESS — unlimited puzzles across all rules, available with a one-time purchase

## Pricing and in-app purchases
