Sisyphus for Eggs! is a Roblox strength simulator built by xFrozen x Dudes, where the whole game comes down to one task repeated at ever-larger scale. You build up raw strength, then shove a giant egg up a hill. Reach the top and the world is cleared, the egg rolls back down to hand you a reward egg, and a portal to the next area opens.
Quick answer: Train strength on the weight pad, hatch pets on your plot for passive cash, spend that cash on stronger dumbbells and base multipliers, then push the world egg to the top of its hill to unlock the next world.
The core loop: strength, cash, and the hill
Every run starts the same way. A level 1 character with zero strength walks up to the first egg and cannot move it an inch. White arrows on the ground point from your plot to the egg track, and a “Tap” prompt appears when you are in position to push.

Two systems feed into clearing a hill. Strength determines how hard you can push the egg, and cash buys the upgrades that raise your strength gains and income. The two grow together: more cash buys better dumbbells, better dumbbells raise strength faster, and higher strength clears the next world.

Worlds unlock in a fixed sequence. Each one has its own egg, its own hill, and its own pets to hatch. Clearing a hill posts an “unlocked” message and tells you to open the Teleport menu to travel there.
| Order | World | Unlocks next |
|---|---|---|
| 1 | Green World | Desert Island |
| 2 | Desert Island | Ice Kingdom |
| 3 | Ice Kingdom | Under Water |
| 4 | Under Water | Final world in the run |
Green World is the gentle introduction. Once your strength passes its low threshold, the egg goes up easily and Desert Island opens.

Ice Kingdom raises the bar sharply. The first attempt there fails outright because the strength that cleared Desert Island is not enough for the icy slope, so a fresh round of upgrades is needed before the egg will budge.

Under Water is the hardest hill in the run. Even after reaching more than 67 Quintillion strength and a base earning over 67 Quadrillion cash per second, the egg still slides back down. The push there was attempted several times without success before the session ended, which marks it as the real wall of the game.
Weight training and dumbbell upgrades
Strength comes from standing on a circular weight pad and lifting dumbbells. The dumbbell you hold decides how much strength you gain per lift, and you buy better ones with cash through the shop menu. The menu is labelled “Treadmill Shop” in-game, but it is the dumbbell upgrade list.

The tiers climb from a plain Dumbbell through themed versions like Strawberry, Nuclear, Frozen, Rocket, Anvil, Burger, and Skull, up to the Rubik Dumbbell, Spike Dumbbell, and Gold Dumbbell. Higher tiers from the Event Pass include the Trex Egg Dumbbell.
Equipping the Prestige Trex Egg Dumbbell from the Event Pass triggers a bug where the weight turns invisible, so the standard Trex Egg Dumbbell has to be used instead.
Pets and passive cash income
Pets are placed on your base plot and generate cash per second on their own. You get them by hatching eggs, and each world adds its own egg types to the hatch pool. Early eggs include Basic (Common) and Frog (Uncommon), while later worlds bring Ocean, dinosaur, and dragon pets.

Income scales dramatically with the right pets. A hatched Brachiosaurus grants a large income jump, and buying Hydras from the shop pushes base earnings up hard. Nine Hydras were purchased in the run, each priced at 12,000 Robux, with one pet line reading $1T/s.
Base multipliers and rebirths
Two cash systems sit on top of your pets. Upgrading your base plot raises your overall cash multiplier, so every bit of income is boosted at once.

Rebirth works the other way around. It resets your current cash progress in exchange for a permanent multiplier on future cash gains. Rebirths stack as you climb, reaching the max rebirth count during the run, which is what pushes income into the quadrillions needed for the later worlds.
Robux packs and shop shortcuts
Several paid bundles let you skip the slow early grind. The Ultra Pack costs 640 Robux and bundles $100 Trillion in cash with two pets, the Winged Evil at $17.5B/s and the Cerberus at $15B/s. Gamepasses add speed and strength multipliers on top.
There are also side activities. Buying trails in the Trail Shop runs through colour tiers from Green up to White. The Egg Run arcade cabinet is a minigame that, on a high enough score, triggers an egg explosion and spawns an egg on your plot.
The game’s loop is simple to describe and brutal to finish: push the egg, grow strong enough to push the next one, and keep going until a hill like Under Water refuses to give, no matter how high the numbers climb.
