First steps in the shop
Step
In short
Buying your first character and watching money roll in is all you need to do to get started.
When you load in, the shop is where everything begins. Your starting cash only stretches so far, so pick the cheapest character available and buy it. From that moment the character works automatically, no input needed.
- Open the shop browse every character listed and find the one you can afford right now.
- Buy the cheapest character your opening budget will not cover the pricier ones, so start small.
- Watch the cash climb the character generates money on its own; you do not have to do anything.
- Reinvest immediately the moment you can afford a second character, buy it so two are earning at once.
- Scroll to the bottom of the shop more characters sit further down the list, so do not assume you have seen them all.
02
Building up your roster
TipsIn short
Stacking multiple characters is the core loop that accelerates your earnings.
Each new character you add runs alongside the ones you already own, so the total cash coming in multiplies with every purchase. Keep funneling earnings back into the shop rather than sitting on a pile.
Tips worth knowing
- Buy more than one character as soon as funds allow — several characters earning together outpace a single one.
- You can buy the same character more than once, which is a fast way to push income higher.
- Check the leaderboard to see where you stand against other players and gauge how your income compares.

Rebirth and what it means
Summary
In short
Rebirthing resets your progress but lets you climb faster on every subsequent run.
Rebirth is the mechanic that keeps the game from feeling like a dead end. Repeating this cycle is how players climb the leaderboard over time.
- Rebirth resets the run and makes the next one more efficient
- First rebirth earns you the Rebirth badge, confirming the milestone
- Leaderboard position improves naturally the more rebirths you complete
05
Floors, gifting, and crates
TipsIn short
Unlocking the second floor, opening crates, and gifting items to other players are all meaningful goals to work toward.
Beyond the core buying loop, the game has a second floor to unlock, crates to open, and an item-gifting feature. Each of these has a badge attached.
Tips worth knowing
- Work toward unlocking the 2nd Floor.
- Open a crate when you get the chance — the Crate Opener badge confirms it is part of normal progression.
- Gift an item to another player to earn the Donator badge.

Common questions
FAQWhat should I do first when I start?
Open the shop and buy the cheapest character available with your starting cash. Once that character has earned enough, buy a second one and keep reinvesting from there.
Why would I rebirth when it resets everything?
Each rebirth makes the next run faster and more efficient than the one before it. Repeating the cycle is how you climb higher on the leaderboard over time.
