How Offline Earnings Work
- Offline income is calculated from the monsters and buildings left in your maze
- A maze with high-traffic corridors and well-placed monsters earns more offline than an empty or badly laid-out one
- Offline earnings are subject to a cap — check the offline panel for the current limit
- Rebirth multipliers apply to offline earnings, which is why rebirth payback feels instant overnight
Pre-Logoff Checklist — Maximize Your Overnight Haul
- Place every monster you own — an unplaced monster earns nothing offline
- Move monsters onto your highest-traffic corridors before logging off
- Move valuable monsters into premium buildings for the payout multiplier
- Spend down cash you cannot use — cash left in the wallet does not earn offline interest
- If you are close to a rebirth threshold, either finish it or wait — do not leave a half-built maze offline
- Confirm the offline panel shows your expected rate before you close the game
Stacking Offline Earnings With Rebirth
- Evening: configure maze, log off
- Morning: collect offline earnings, evaluate rebirth threshold
- Morning: rebirth if the multiplier pays back within a session
- Rebuild the known-good layout and repeat
Offline Earnings Mistakes
- Logging off with unplaced monsters sitting in inventory
- Logging off mid-rebuild with an incomplete corridor layout
- Leaving cash unspent that could have bought a monster before logoff
- Ignoring the offline cap — beyond it, extra monsters add nothing until you log in and collect
- Rebirthing right after collecting without rebuilding first — you waste the following offline window
