Mental Battle

MentalBattle - competitive mental arithmetic, in real time.

Challenge other players in fast duels where every second counts: 20 calculations, 2 minutes, and a live leaderboard that shows exactly where you stand.

- DUEL 1V1 AND MULTIPLAYER (2 TO 8)
Quick match search, lobby creation, or join with a code. A synchronized 3-second countdown opens every game, and the score stays authoritative from the first calculation to the last.

- SOLO CAMPAIGN: 200 LEVELS
A fixed campaign whose difficulty rises at every single level. Each level is 2 minutes and 20 calculations, and unlocks the next one. Subtraction, multiplication, signed operands, exact divisions then three-operand expressions with brackets appear as you climb. Clear a level in under a minute to log a fast session, replay any unlocked level, and chase your best time.

- DAILY CHALLENGE
The same 20 calculations for every player, every day, with a fixed difficulty of its own. One recorded attempt per day, no time limit, your daily streak, and a share button for your time.

- DAILY LEADERBOARD
The fastest times of the day, ranked. Sign in to publish your run under your pseudo.

- TRAINING MODE
No pressure and no clock: solve as many calculations as you can, track your streak and your elapsed time.

- STATISTICS AND TROPHIES
Games played and won, win rate, best streaks, perfect games, average calculations per game, total play time, a detailed Solo section, and dozens of trophies to unlock across several categories.

- YOUR ACCOUNT, YOUR PROGRESS
Create an account with an email address or continue with Google, pick your unique pseudo and synchronize your statistics, trophies, Solo progress and daily challenge across your devices. You can also play entirely offline - your progress then stays on that phone.

- RETRO LOOK, MODERN FEEL
A retro interface with music and sound effects you can mute independently, in a fast and uncluttered flow.
