There are 2 galaxies with 40 worlds each. Unlock new worlds with wins. Each world has its own eggs, and every world makes your jump and your wins 10 times bigger than the one before. You keep your pets, and you can travel back any time.
At 100B wins you can rebirth. Your wins go back to 0 and all your pets are deleted, except 1 pet you pick to keep. Every rebirth adds +1 to your rebirth multi, which boosts both your jump and the wins you earn. With more wins you get more rebirths at once: every 1,000 times more wins gives about 6.7 times more rebirths (1,000 ÷ 150).
Like rebirths, but better, and nothing resets: you keep all your wins, pets, rebirths and worlds. Your first ascension needs 1e1000000 wins, and each one after that needs another million zeros (1e2000000, 1e3000000 ...). Every ascension makes your jump and your wins 10 times bigger.
Spend wins on eggs. Every egg has 5 pets. The rarer the pet (lower %), the bigger its jump multi. Pricier eggs hold stronger pets.
Equip up to 4 pets. Their multis add together: jump multi = 1 + your 4 pets. Tap a pet to equip or unequip it.
Put 3 of the same pet in, get 1 pet out with double the jump multi. Crafted pets can be crafted again: Normal, then Big (x2), then Huge (x4), then Mega (x8).
Your best wall goes on the board automatically. Same name as the other GH Games.
Type a friend's in-game name and send them wins or one of your pets. You can only give what you have, and it leaves your game straight away. Gifts arrive while their game is open. Both of you need a name set.
