Drowning Math: Mental Math

Solve fast or sink. Drowning Math is a mental math game that turns arithmetic into a survival race: every right answer swims you up, every mistake drags you under. How long can you stay afloat?

HOW IT WORKS
You sink a little every second. Pick the right answer out of three before the 5-second timer runs out and you swim up; miss and you drop. Stay below the oxygen line and your HP drains away.

DAILY CHALLENGE
One board, the whole world. Everyone gets the same puzzles today, with its own leaderboard that resets at midnight. Come back tomorrow for a fresh one.

SEVEN MENTAL MATH MODES
• Daily Challenge — today's board, the same for everyone
• Classic — survive as long as you can
• Chain — each answer becomes the start of the next problem
• 60 Seconds — no HP, pure speed: score as much as you can before the clock runs out
• Sudden Death — one life; the first mistake ends the run
• Division — find the number hidden behind the ? tile (experimental)
• Training — no lives, no timers, no scores; practice at your own pace

BRAIN TRAINING THAT NEVER STOPS GETTING HARDER
Start with single-digit sums. Every 10 points you level up: three-term problems, then multiplication, then exact division, with bigger numbers at every level and no ceiling. Three answer options with carefully chosen wrong ones, so guessing never works.

GLOBAL LEADERBOARDS
A global top 50 for every mode, plus a fresh Daily board every day. No account needed: type a name and submit your score. Beat your best, then beat the world.

BUILT FOR SPEED
No sign-up, no lessons. Tap Play and you're in. Runs are short, perfect for a coffee break or the bus, and an optional daily reminder tells you when a new board is out.
