## What is Trio Math?

Sharpen your mental math skills with Trio.

Find hidden Trios in the number grid by selecting three numbers in a row and calculating their result to match the target number. Each valid Trio must include one multiplication and one addition or subtraction - no simple sums allowed. Multiple solutions exist for each target number, so think strategically and act fast to earn three stars.

How to play:

    Find three numbers that form the target number
    Use one multiplication and one addition or subtraction
    Think creatively - brackets are allowed

For example, to reach 9, you could choose:

    3 × 5 - 6 = 9
    5 + 2 × 2 = 9
    (6 - 3) × 3 = 9

But using two additions is not allowed:

    5 + 2 + 2 = 9 (No multiplication used)

Features:

- Daily Challenge Mode – Solve two out of three puzzles in unique game modes
- Global Leaderboard – Compete with players worldwide and track your success
- Jokers – Stuck? Hold a number to swap it for a Joker and find new solutions
- Ad-Free, Privacy-Friendly – No ads, no data collection—just pure gameplay

Trio is free to play, but if you enjoy the challenge, you can support development by unlocking the MinusTrio game mode. Whether it's the cost of an espresso or a cappuccino, your contribution helps keep the game growing.
