Manage your factory, watch numbers grow, and improve it endlessly.
Dumbers is an automation game where you extract numbers, process them with math operations, and deliver to the Hub to progress through infinite levels. Focus on building and refining your factory step by step.
15 UNIQUE BUILDINGS
• 5 Extractor Tiers (T1 to elite T5)
• Mathematical processors that add and multiply the collected items (Adders, Incrementers, Doublers, Triplers, Quadruplers)
• Transport & Logistics (Belts, Express Belts, Mergers, Splitters)
No complex math needed: relax as numbers multiply and flow through your factory.
Smart design beats brute force. Processor placement matters:
• Synergy Bonuses: Chain processors strategically for up to +30% bonuses (ADDER → MULTIPLIER, INCREMENTER → ADDER, ADDER CHAINS, MIXED combinations)
• Diminishing Returns: The more processors a resource passes through, the smaller the gain from each one — and longer chains also become slower. Optimize your production lines wisely!
• Dynamic Penalties: Excessive splitters, mergers, and logistics abuse reduce final output at the Hub
• Real-time Feedback: Visual indicators show efficiency and penalties as numbers flow through your factory
Build diverse, efficient layouts instead of spamming the same buildings.
Resources have dual use: level up to unlock new buildings, or invest in permanent upgrades for production boosts. Every choice enhances your factory's efficiency.
Boost extraction speed, cut processing time, speed up belts, and more. Unlock bonuses like Lucky Extractor (2x random values) and Processor Efficiency (extra outputs). Each path has 5 progressive levels.
• Pause anytime for planning
• Color-coded buildings with efficiency indicators
• Satisfying particle effects and animations
• Idle progression—factory runs while away
• Multiple save slots and auto-save
• Are you tired of placing buildings, or have you reached high levels and the resources you obtain no longer matter? Press Z and admire Zen Mode as you travel through numbers!
15+ levels with growing targets. Beyond level 15, challenges scale infinitely.
Design efficient layouts. Discover optimal synergy combinations. Master the balance between diversity and optimization in your factory.
