Best Upgrades for Your Run

Match your next upgrade to hotter logs, more income, temporary rain protection or easier fuel handling.

Upgrade Tree

Open the upgrade panel, reveal further purchases and look up early upgrades, fuel unlocks and later equipment.

Spawners and Automation

Buy and place spawners safely, distinguish fuel production from delivery and choose upgrades that reduce manual feeding.

Progression Goals

Connect upgrades, fuel unlocks, automation and storm survival as you work toward Level 50 and later worlds.

Level Up Toward Level 50

Raise fire level with repeated burns, reinvest in earnings and fuel production, and respond to levels lost during storms.

Fuel Unlocks

Find lightning, explosive and firework unlocks in the upgrade tree, use their effects and recognize later fuel options.
