About This Package
SPARK & SURGE
It starts with a single click and one point of Energy. It ends with reactors that burn dark matter, machines older than the universe, and numbers that need new names.
Strike the Energy Core to generate Energy. Click fast to build a combo multiplier, chase critical surges, then spend everything on upgrades and automated machines that keep producing while you plan your next move, from a humble Mini Generator to Quantum Reactors, Antimatter Forges and the Omega Reactor.
When your run has given all it can, Rebirth. You lose the Energy, the upgrades and the machines, and gain Cores, a permanent multiplier, and access to things the last run never saw. Every reset makes the next one faster.
Dig deep enough and you'll turn up Ancient Cores: vanishingly rare relics that buy permanent upgrades and machines which survive every Rebirth. They're the only things you never lose.
Features
- 20+ upgrades and 17 machines across a long escalation curve
- Rebirth prestige with a permanent upgrade tree
- Ancient relics - a rare currency with its own tier of unlosable content
- Combo and critical click systems that reward fast hands
- Achievements, daily rewards and detailed lifetime statistics
- Global leaderboard ranking the biggest single run ever recorded
- Runs in your browser, saves automatically, plays in short bursts or long sessions

The Surge Update
Aug 10, 2026
Added
- SURGE — a brand new prestige layer beyond Rebirth. Once you have claimed every Rebirth milestone you can trade in your entire Rebirth career for Surged Cores.
- Surge Shop — spend Surged Cores on six upgrades that nothing in the game can ever take away, not even another Surge.
- Gigawatt Crits — push your combo into the red and a critical can detonate for triple damage. If it is the click that finds a relic, it drops two Ancient Cores instead of one.
- Six new Energy upgrades, including the first ones to exist past 12 Rebirths.
- Seven new machines, filling the old gap in the middle of the ladder and extending it from 20 Rebirths out to 33.
- Later Ancient epochs — five more Ancient upgrades and six more Ancient machines, unlocked at 15, 30, 50 and 75 Rebirths, so the Ancient tab keeps growing instead of being finished the day it opens.
- Sixteen new achievements, reaching out to a sextillion Energy, a 250x combo and 150 Rebirths.
Improved
- The Energy Core is alive — it breathes while idle, throws an expanding shockwave every time you strike it, and visibly heats up as your combo climbs.
- Crossing a combo tier now has its own ring and rising tone, so you can hear the multiplier step up.
- Criticals land harder on screen: a brighter flash, a heavier ring and a bigger burst of sparks.
- Sparks take on your combo's colour, shifting from cyan through orange to red as the streak builds.
- Singularity Engine and Omega Reactor were poor value for their price and have both been buffed.
- The Rebirth panel now shows exactly how much Energy the next Rebirth needs, and why.
- Locked machines and relics now show what unlocks them instead of appearing available.
Fixed
- Global rankings never appeared in game. The leaderboard now reads live data and works.
- Rebirth could be spammed once you owned Ancient machines, because they keep running through a Rebirth and instantly re-earned the requirement. The requirement now scales with the income that survives a Rebirth.
- Rebirth milestones could be farmed by repeatedly resetting cheap runs. They now also require a single Rebirth large enough to earn the Cores shown.
- Milestones at 3, 10, 35 and 75 Rebirths granted their permanent bonus silently, with no notification at all.
- Ancient relics you had not unlocked yet showed a buy button that did nothing.
- The game could hang permanently on the loading screen and never recover.
- Achievements had stopped unlocking entirely.
- Almost nothing was being submitted to the global leaderboard.
- Newer machines and Ancient content were sometimes invisible, or could not be purchased.
- The Rebirth and Awards panels could not be scrolled and their text overlapped.
- The background showed a hard horizontal seam across the screen.
- The hover sound repeated rapidly while moving the cursor across a single button.
- Long machine names squashed the "N owned" badge beside them.
- The Reactor's icon rendered as a green X.
