Nova Chain: Chain Reaction

Tap the void, ignite a nova, watch the chain explode! Combine Cores and push your score into the billions. An endless cosmic run, fully offline.

Tap the void. Ignite a nova. Every orb it touches explodes too, the chain grows and the numbers fly!

Nova Chain blends the instant thrill of a chain reaction with the depth of a roguelite. It takes one finger and one second to learn, and much longer to master.

• ONE TAP, MASSIVE CHAINS Every spark starts a cascade. The longer the chain, the higher the music climbs, the harder the screen shakes, and time slows down for the big moments.

• ENERGY × MULT Quartz adds Energy, Amber adds Mult, Prism multiplies it. Scores climb from hundreds to billions.

• 28 CORES Gravity Well, Domino, Supernova, Infinity Loop… Combine Common to Legendary powers into your own broken build.

• FROST, BOMBS, BLACK HOLES New orbs unlock as you go deeper, and a boss waits every third sector.

• ENDLESS SECTORS There is no final level. How far you get depends only on your combos.

• PERMANENT PROGRESS Earn Stardust even when you lose. Unlock upgrades, 5 nova themes and 19 achievements in the Observatory.

• DAILY RUN AND REWARDS A new universe every day, plus login streak rewards.

• FULLY OFFLINE No ads, no account, no internet needed. No data collected.
