Angler's Cove — Fishing Simulator
🐟 Cast, fight & land 18 real species — and keep it legal • Free for Everyone • No Account
Run a sport-fishing career across four waters, from a quiet lake to the open ocean. Charge the cast, strike in the hookset window, and fight the fish on a live tension line — reel too hard and it snaps. Drive the boat to the deep spots, fill a species encyclopedia with real biology, and respect legal lengths, bag limits and protected species— or the warden meets you at the dock and takes your license.
Singularity — Black Hole Simulator
🌌 Grow from cosmic dust to the centre of the universe • Free • No Account
Begin as a single mote of dust and drive through real-time gravity, swallowing everything smaller than you. Snowball through asteroids, real-textured planets, and blazing stars, collapse into a black hole, and devour the galaxy — with a real astronomy data card on every object you eat (yes, including the actual red Tesla SpaceX launched into space).
Marine Biology Simulator
🤿 Become an ocean scientist on a living coral reef • Free for Everyone • No Account
Dive a vibrant 3D reef teeming with real species — from clownfish and sea turtles to whale sharks, orcas, and a prowling megalodon. Scan creatures to build a living encyclopedia, collect samples and analyze them in the lab, clean up the reef to restore its health, and follow a guided campaign of missions that earns you the rank of Master Naturalist.
Alchemy Simulator
🧙 Brew real chemistry in a candlelit wizard's tower • Free for Everyone • No Account
Step into an alchemist's workshop lit by hearth-fire and moonlight. Gather ingredients from the shelves, brew them in the iron cauldron, and discover transmutations powered by real chemistry — alloys, acids, pigments, even plastic made from milk. Fill your grimoire, rise from Apprentice to Grand Alchemist, and earn the Philosopher's Stone — then learn the truth about turning lead into gold.
Research Lab Simulator
⚖️ Real quantitative chemistry — weighed in grams • Free for Everyone • No Account
A working research lab with every real element (118) and hundreds of real compounds — solids, liquids, gases and solutions. Weigh reagents on the digital balance, react them in the flask, and get true stoichiometric results: moles, limiting reagents, actual yields in grams, and what's left over — straight from the balanced equation, like a real chemist.
Tornado Simulator — Stormrunner
⛈️ YOU are the tornado — survive the 50-mile swath • Free for Everyone • No Account
Spawn as a funnel cloud inside a supercell and ride a 50-mile storm corridor. Follow warm inflow, convert wind shear, dodge dry air and cold outflow, and grow from funnel to EF5 — leaving a real damage path through farms, towns, forests and industry. When the atmosphere starves you, feed on destruction to stay alive. School-safe: every person and animal evacuates to shelter, always.
Bot Arena — Battle Robotics Simulator
⚔️ Build your battle robot, then survive the cage • Free for Everyone • No Account
Pick from a 20-bot roster — wedges, spinners, flippers, hammers, walkers, even a humanoid mech — then customize paint, weapons, armor and mobility with real engineering tradeoffs. Enter the rocket-glass combat cage against AI opponents with personalities, where floor saws, hammer posts, the pit, shock panels and conveyor beltsare as dangerous as the other robot. Win by knockout, flip, pit-drop, or judges' decision.
Tree Masters — Arborist Simulator
🪓 Climb, prune & fell like a pro • Free for Everyone • No Account
Run a real tree-care career. Identify the species, climb up and diagnose the defects — deadwood, cracks, codominant stems, root rot — then prescribe the correct ANSI A300 plan. Make proper collar cuts with the 3-cut method, respect the 25% rule, and take whole trees down with a real notch & hinge. Graded like an ISA certification exam, from backyards to storm response to champion old-growth.
Lineman — Storm Restoration
💡 The storm hit — bring the power back • Free for Everyone • No Account
The third act of the storm trilogy: the tornado hit, the trees came down, and now the street is dark. Patrol the line, diagnose the fault, dress out in the right PPE and rubber-glove class, then run the sequence that keeps linemen alive — isolate, test before touch, ground, repair, re-energize— and watch the lights ripple back on down the street. Grounded in real OSHA line practice, graded like an apprenticeship from groundman to transmission troubleman.
PipeMaster — Plumbing Simulator
🚰 Diagnose, cut, join & pressure-test — don't flood the house • Free for Everyone • No Account
Run a real plumbing career. Diagnoseleaks, clogs, dead water heaters and burst pipes, pick the right pipe — copper, PEX, PVC, CPVC — and the right join — solder, solvent-weld, crimp— then run the safe-work sequence: shut off, drain, cut, join, pressure-test. Cut a live line without shutting the water off and you flood the house. Real plumbing code — P-traps, drain slope, the T&P valve, backflow — from service calls to full new-construction rough-in.
GreenKeeper — Landscaping Simulator
🚜 Mow every blade, miss every sprinkler • Free for Everyone • No Account
Run a lawn-care crew. Drive the mowerto cover every patch of grass — with real mowing stripespainting the lawn behind you — shape the overgrown hedges, edge the walks and blow the property clean. But mow aroundthe pop-up sprinkler heads hidden in the grass, or you'll geyser the yard. Real agronomy — the one-third rule, mow high, sharp blades — from suburban yards to commercial grounds and formal estates.
PestPatrol — Pest Control Simulator
🐜 Inspect, identify, treat — the IPM way • Free for Everyone • No Account
Become a pest-control technician. Inspectthe home for evidence — droppings, trails, mud tubes, nests, entry points — identify the pest from the clues, then choose the least-toxic targeted treatment: exclusion and bait beat blanket spraying. Contaminate the kitchen counter, the kid's toys or the pet bowl and it's a failed callback — and the honey bees get relocated, never sprayed. Real Integrated Pest Management, where the label is the law.
