About This Package
💥 Drop. Detonate. Compound. 💥
One bomb, a board full of chests, and the quiet satisfaction of watching a single
click turn into forty explosions you didn't have to pay for!!! 💥
Chain Reaction is an idle reactor built around ONE moment : the cascade.
Chests pile onto the grid, drones drop their payload, and everything that dies takes its
Chests pile onto the grid, drones drop their payload, and everything that dies takes its
neighbours with it. 💣
Bank the Cores, buy the upgrade, watch the next cascade run
Bank the Cores, buy the upgrade, watch the next cascade run
longer than the last. Then leave, and come back to a pile of Cores waiting for you.
🎯The board runs itself. You make it run harder. 🎯
The reactor never stops feeding: chests drip in, the hopper tops the board up before
every cycle, drones arm and detonate on their own. Your job is the economy around
it — wider warheads, tighter fuse timing, richer chests, more bomb chests to carry
the chain further. Every upgrade lands on the very next detonation, and you can see
it land.
When you want your hands on it, they're on it. Overload fires the board manually.
Surge doubles everything while the charge lasts. Golden chests appear on a timer and
disappear if you're not quick.
💣Meltdown, and start again bigger! 💣
Cores buy the upgrades. Upgrades run out of room. Melt the reactor down and the whole
cycle converts into Flux. The currency that never resets ; then buy the perks that
make the next run outclass the one before it.
Underneath both sits the pet : Fragments condense slowly on a daily ceiling and feed a
permanent output multiplier that takes weeks, not hours. It survives every reset you
will ever do ;)
💰 Come back to progress! 💰
Offline earnings run while the game is closed, up to a cap you can raise. Daily bonus
on the way back in. Achievements that are visible from the first minute so you always
know what the next thing is!
📈Then find out where you stand!📈
Global leaderboards for total Flux earned, longest chain sequence, best score and pet
level — top 100 on each, with medal tiers for the players holding the top of the
board. Every detonation is a number, and every number goes somewhere :)
🚀 In the reactor 🚀
- A board that plays while you watch — drones, hoppers, chain fuel, cascade payouts
- Upgrades with immediate feedback — warhead class, fuse timing, chest value, gem rate
- Meltdown prestige — Cores reset, Flux and perks don't
- A pet on its own clock — daily Fragments, permanent multiplier, weeks-long goal
- Offline earnings and a daily bonus — the reactor works the shift you don't
- Golden chests, Surge and Overload — three reasons to keep a hand on the mouse
- Achievements and global leaderboards — the long tail after the numbers get big
GOOD LUCK! =)
