Free route logic
Without exact public cost tables, the safest advice is to spend around the slowest part of your current loop.
- Empty board: improve spawn rhythm.
- Full board: merge and clear space.
- Raid losses: protect before attacking.
Upgrade bench
Merge a Nuke upgrades and bottleneck choices
Upgrade the blocker you can feel: spawn speed if the board is empty, auto merge if manual combining slows you, lock cooldown if raids punish you, and health if nukes are getting deleted.
Premium pass signals
Use pass names and live shop text to understand which part of the loop a purchase improves.
- Auto Merge: Best for players who leave income running and want less manual combining.
- x2 Spawn Speed: Strong early momentum if your bottleneck is waiting for new bombs.
- x2 Nuke Health: Defensive value for raid-heavy servers where nukes get pressured often.
- Quick Nuke Cooldown: Good for active raiders who launch frequently instead of idling.
- Quick Lock Cooldown: The clearest budget defense pass because base locks are central to the core loop.
Avoid waste
Do not buy or upgrade around a problem you do not have. A player who idles mostly needs different help than a player who raids every minute.
- Idle players value automation.
- Raiders value cooldowns.
- Defenders value lock and health tools.
Use it in game
- Name the current slowdown.
- Spend only on that slowdown.
- Run one merge and raid cycle.
- Compare cash pace before buying more.
- Review after Friday changes.
