Lilymere: Pond Ecosystem Idle

An idle pond with a real food chain: balance algae, water fleas and minnows, grow lily pads and deepen a puddle into a lake through herons, heat waves and spawning. Free, no ads, no tracking; mouse, touch or keyboard.

Lilymere is an idle pond. Algae, water fleas and minnows rise and fall together; lily pads turn a balanced pond into petals.

Keep each population inside its green band, ride out herons, heat waves and spawning seasons, and deepen the pond five times.

• A living food chain: algae, fleas that graze them, minnows that eat the fleas
• Balance pays: income depends on how healthy the pond is
• Lily pads shade the water: more petals, but less algae for the fleas
• Events: herons, heat waves, rain and spawning
• Live graph of the last minutes
• Six stages from puddle to lake, offline earnings, fastest time saved
