Understanding the Laboratory Economy

Monster Lab Simulator features a complex economic system where every decision impacts your profitability. From breeding costs to selling strategies, understanding the economics is crucial for building a successful laboratory operation.

The economy revolves around three core pillars: Breeding Costs (essence prices and incubation fees), Selling Prices (based on rarity and stage), and Money-Making Strategies (optimized workflows for maximum profit).

This guide provides comprehensive formulas, ROI calculations, and proven strategies used by top-tier laboratory operators to maximize their coin generation and build sustainable economic foundations for long-term success.

Economic Mastery Timeline

Beginners can start with Neri Farming (Day 1), progress to Fusion Flipping (Week 1), and master Arena Rewards and lottery systems (Week 2+). Each strategy builds on the previous, creating a sustainable economic progression path.

Money-Making Strategies

1

Neri Farming (Beginner Strategy)

Concept: Mass-breed the cheapest Common monster (Neri), grow them to Adult stage, and sell for consistent profit. This is the foundation strategy for new players building their initial capital.

Step-by-Step Neri Farming

  1. 1. Purchase 10× Fire, Water, Nature essences (bulk discount: 135 coins per set)
  2. 2. Breed 10× Neri eggs (cost: 155 coins each = 1,550 coins total)
  3. 3. Incubate all eggs (5 min each, can run 3 incubators in parallel)
  4. 4. Grow Hatchlings to Adult (feed 3× per monster, 15 min total)
  5. 5. Sell Adults at 255-289 coins each (average: 272 coins)

Breeding Cost Formula

Total Cost = Σ(Essence Costs) + Incubation Fee

Example: Fire + Water + Nature (Common)

= (50 + 50 + 50) + 20 = 170 coins

Bulk Breeding Optimization:

When breeding 10+ of the same recipe, use bulk discount pricing:

= (45 + 45 + 45) + 20 = 155 coins per monster

Savings: 15 coins per monster (8.8% reduction)

2

Fusion Flipping (Intermediate Strategy)

Concept: Buy underpriced Common monsters from the market, fuse 3 into 1 Epic, then sell the Epic at a premium. Works best when Common prices dip below their synthesis cost.

Flip Formula

Buy 3× Common @ market price

Fuse → 1× Epic

Profit = Epic sell price − (3 × buy price)

4

Amber Smelting (Mid-Game Strategy)

Concept: Collect Amber Fragments from monster drops and smelt them into Amber Ingots. Ingots sell for 3–5× the raw fragment value.

Smelting Rates

  • 5× Fragments→ 1× Ingot
  • Fragment value40 coins each
  • Ingot sell price600 coins
  • Profit per smelt+400 coins

Bingo Machine Lottery

Concept: Spend Bingo Tickets (earned from daily quests) on the Bingo Machine for a chance at rare monsters, essence bundles, and coin jackpots. Expected value is positive at 1.4× ticket cost.
