How to Play

Simultree’s gameplay fuses incremental mechanics with accessible simulation fun. When you start, you’ll see a lively grid populated by your basic entities—adorable creatures striving to survive. Your central goal is simple: guide their evolution by ensuring they eat, grow, and multiply!

Begin by observing your entities as they move around the grid, searching for fruit. With each fruit eaten, your creatures gain energy, fueling reproduction and unlocking new genetic possibilities. As life blossoms, use your rewards to access upgrades in the branching tech tree. Every upgrade changes something fundamental, introducing new traits, abilities, or gameplay mechanics to experiment with.

Navigate the interface with intuitive mouse clicks—select upgrades, advance simulation time, and interact with objects in your ecosystem. Monitor stats and resource bars to optimize your entities’ survival and development. Every run is finite, but each failure feeds directly into progress: unlock powerful traits over time, opening up higher scores and chances to top the leaderboard.

Beginner tips: Focus your early upgrades on survival essentials like fruit yield or reproduction efficiency. Keep an eye on balance—overpopulation can collapse your simulation! Experiment with your options and don’t fear failure; every setback is a leap forward in Simultree’s unique incremental evolution system.
