Split-screen math battle on the same device. Every problem gives you one second to tap TRUE or FALSE - first wrong answer loses.

Tap TRUE if the statement is correct. Tap FALSE if it is wrong. Stay alive by answering fast and accurately. FIVE DIFFICULTY LEVELS • Easy - Simple addition for quick starts • Normal - Addition and subtraction with more pressure • Hard - Bigger numbers and multiplication • Super Hard - Three-operand problems at relentless speed • Mix - Starts easier, then escalates as you survive LIVE LEADERBOARDS Track your best scores across five live leaderboards.
