The Best Rebirth Levels for ROI
R5 → R6: First major income jump. The +35% bonus you get plus the Ruby Slap unlock easily pays for itself within a day of normal grinding.
R10 → R12: A well-timed push. Cash is plentiful at this stage from earlier multipliers, and R12 is the gateway to T-tier income.
R15: The single best level. The +60% multiplier from R14→R15 is the largest single jump in the table, AND R15 unlocks a class of gear only available at this tier. Most players plateau at R10-12 and miss out.
Mistakes to Avoid
- 1Rebirthing too early: Each rebirth costs cash, and rebirth costs scale fast. Save up to do 2-3 rebirths in a row to amortize the time-loss
- 2Forgetting gear unlocks: Many gear slots only open at specific rebirth levels. Check the gear shop before each rebirth so you know what's coming
- 3Stopping at R10: The +50% from R10 sounds nice, but R15's compound multiplier is 4× larger when you actually do the math
How to Get to R15 Fast
- 1Stack 3-5 Cyber Secrets first (Los Chillis, Digi Narwhal). Each one earns billions/sec
- 2With $100B/s combined income, $25T (R14 cost) takes ~70 hours of passive earn. Cut that with weekend Cyber windows
- 3Buy your traits and Steal Shield BEFORE rebirthing — those carry over
R15 is achievable in ~3-4 weeks of solid Cyber-era play. After that, R20 takes another 2 months but the grind is mostly idle once your top earners are stacked.
