NumReactor

The core is glowing. The target's ticking. Can you solve it in time?

Number Reactor is a fast, tense arcade game built around mental math under pressure. Stones orbit a reactor showing a target number, and you tap the ones that combine to reach it. Solve it right, and the reactor cools. Get it wrong — or too slow — and the heat climbs. Let it max out, and you watch the whole thing melt down.

FEATURES • Simple to learn, brutal to master — pure mental math under pressure • Combo system rewards fast, accurate chains of correct solves • Heat mechanic keeps every round tense — one bad streak and it's over • Decoy numbers and near-misses keep you honest — the obvious answer isn't always right • Difficulty ramps as your combo grows, so the challenge never goes stale • No ads, no accounts, no network connection — just you and the reactor • Built for one-handed portrait play, anywhere, anytime

Chase your best score, keep your composure, and don't let the core blow.
