Number Factory

Number Factory is an idle game about running a facility that produces ever-larger numbers. Generators produce numbers automatically, including while you are away. You spend your earnings on generators and multipliers, then reset for permanent bonuses when production slows. Each cycle can progress faster than the last.

Grow your production

Start with a generator producing 1 number per second and build up to dozens of maxed generators. Upgrades compound your growth, while automatic formatting displays values from thousands (1.5K) to vigintillions (1.5Vg) and beyond. The game tracks production rates, total playtime and other statistics, along with personal records.

Prestige and challenges

When you reach a limit, reset your progress to earn Prestige Points and Formula Energy. Spend these on permanent bonuses in an extensive prestige tree, with dozens of upgrades that can focus on production, prestige point gains or new mechanics. Skills let you specialize in production, prestige gains or automation. Special challenge modes restrict your abilities in return for rewards, and completing them unlocks unique bonuses.

Achievements and competition

The game includes hundreds of achievements for milestones from your first million to your billionth prestige. You can earn Crystals through gameplay, spend them on production multipliers or quality-of-life upgrades in the shop, and compete in monthly leaderboard seasons. The leaderboards track highest numbers, most prestiges and total purchases.

Shop and boosts

The shop offers permanent production multipliers, Crystal packs and supporter packs. Production boosts include bonus Crystals and stack multiplicatively. Number Factory has a clean interface, offline earnings and cloud saves.
