Star Kiln is a lightweight idle game: click the kiln for heat, spend heat on stokers that generate passively, and prestige to reset progress for a permanent multiplier.
It runs in the tab while you read or play another SolitaireFelt game — progress saves locally.
How to play Star Kiln
- Click the kiln to earn heat.
- Buy upgrades and stokers that add heat per second.
- Prestige resets buildings but grants a multiplier to future earnings (available at 5000 heat).
Strategy tips
- Buy the cheapest heat-per-second upgrade first until costs outpace gains.
- Prestige when the next stoker would take longer to afford than a reset bonus pays back.
- Leave the tab open briefly — idle gains accumulate while you play elsewhere on the site.
- Click bursts help early; midgame is mostly automation math.
- Track multiplier before prestige — resetting too early slows long runs.
