The Big Number description
The Big Number
Break through a series of increasingly powerful firewalls that block your path. Each firewall gate requires millions to quintillions of damage to defeat and, once cleared, unlocks permanent multipliers that accelerate all future runs.
How you attack
- Manual Clicks – your primary source of damage, tapping your way toward the next gate.
- Security Nodes – red pulsing critical-hit nodes that deal an instant 5% of firewall HP per hit.
- Brute Force RAM – automated attacks that chip away at firewalls over time.
Prestige and progression
When progress slows, reset your run to gain Entropy, a prestige currency that unlocks permanent upgrades. Each prestige provides increasing bonuses, and Entropy can be spent on powerful upgrades to accelerate future attempts:
- Production multipliers (2x, 5x, and beyond)
- Click power amplifiers (3x, 10x, and more)
- Starting RAM bonuses
- Firewall damage amplifiers
- Offline earning boosts
RAM MANAGEMENT
Distribute your RAM across seven distinct processes to optimize your run:
- Mining – boosts auto-generation up to 10x.
- Brute Force – auto-attacks that increase firewall damage up to 4x.
- Cooling – reduces heat generation up to 50%.
- Decryption – multiplies click power up to 5x.
- Virtualization – generates Entropy passively (capped at 100/s).
- Compression – reduces upgrade costs up to 80%.
- Click Boost – amplifies click power up to 200%.
Farm for boosts
Plant crops that grow over time and harvest Data Points. Use these to purchase temporary boosts (production, click power, and more), unlock advanced crops with better yields, upgrade boost effectiveness, and expand your farm with more crop slots.
