About this game
Era Idle compresses the great civilization-idle formula into one clean vertical loop. Two tap buttons gather food and wood; eighteen buildings across six eras turn those resources into population growth, science and culture. Population multiplies every output, science and culture together unlock the next era - Stone, Bronze, Iron, Industrial, Information and finally the Sea of Stars - and each era ships three new buildings with costs and outputs an order of magnitude grander. The twist that keeps it honest: science has its own humble source in the early totem, so every civilization starts by carving meaning before it can carve bronze. Leaving the game is part of the design - offline progress accrues at half rate for up to eight hours, and a welcome-back parcel shows exactly what your civilization achieved without you. Era upgrades fire a celebration and bank your culture as a score, era by era, from fire pit to starport.
How to play
Tap the two ground buttons to gather food and wood, buy buildings from the panel, and reach the science and culture thresholds to advance the era.
Tips & Tricks
- Buy the culture totem early - it is the only science source before the Bronze Age
- Keep food income above population consumption or your pop will stall
- Era thresholds double roughly every step; stockpile before you push
- Offline gains cap at 8 hours at half rate - log in, spend, repeat
