Not "are you good at maths". Sharp. Fast, precise, adaptable under pressure.
Most people have never had an honest answer. Eureka gives you one, and then
gives you something better: a way to make it climb.

Take the 90-second test. You'll get a number.

THE NUMBER
Your Sharpness is a single lifetime rating, from 200 to 2000. It is not a
score, and it is not how much you've played. It's a measure of how well you
think under a clock — and it moves after every rated run.

Eight bands stand between you and the top:
Explorer → Thinker → Scholar → Professor → Inventor → Newton → Tesla → EINSTEIN

Most players never see the last two. That's the point.

HOW YOU CLIMB
Each run gives you a score out of 1,000 — that run, and that run only.
Your Sharpness is the bigger story underneath it.

Here's the rule that makes it honest: harder difficulties can lift your
rating higher, and a run below your level can NEVER lower it. Easy tops out.
Medium takes you further. Only Hard and Expert reach the highest bands.

So you can play relaxed without risk — but you cannot bluff your way up.
The rating has to be earned.

THE GAME ITSELF
Merge numbers with + − × ÷ to hit a target exactly. Every number used once.
Sixty seconds. Ten puzzles a run.

Simple enough to learn in one screen. Hard enough that "Einstein" means
something.

RANKED BY BRAINS, NOT BY LUCK
Three leaderboards, each answering a different question:
⭐ RATING — who is genuinely sharpest, right now
📅 DAILY — one shared puzzle set, the same for everyone on Earth, every day
🏆 BEST RUN — the all-time hall of fame for single-run scores

Filter any of them from worldwide down to your own city, or to just your
friends. And if you're ranked #412, you'll see #412 — not an empty screen.

EVERY DAY, SIXTY SECONDS
• DAILY CHALLENGE — identical puzzles worldwide, one ranked attempt, then
replay untimed as much as you like
• STREAKS — milestone rewards, and freezes so one busy day doesn't erase
a month of work
• LIVE SHOWDOWNS — twice-daily events where you race the world in real time
• FRIEND DUELS — send a link, your friend plays your exact puzzles
• JOURNEY — a levelled campaign to sharpen up on your own terms

MADE TO BE PLAYED DAILY
