Use the price displayed in your current server. This tool does not provide or verify a crate price.
Enter the live price and your current cash to see how many attempts fit the budget.
Formula: maximum attempts = floor(current cash ÷ crate price). All values must use the same in-game unit.
Use what you know from your current server. Unknown answers are valid and keep the plan conservative.
Worker checklist
Start with workers, codes status, crate progress, and Roblox-listed basics.
Add a cash goal if you want the checklist to keep your next target visible.
The Roblox description says liking the game and joining the group can unlock 2 free workers. Check that before optimizing crates.
Read the source contextUse your current crate note to track what unlocks next. Compare the partial dated crate reference with the current pad before spending.
Read the source contextCompare the dated first-Rebirth snapshot with every requirement, reward, and reset warning displayed by your live panel.
Read the source contextThis planner uses supported mechanics and player-entered context. It does not calculate exact cash rates, crate costs, worker scaling, friend multipliers, or Rebirth timing without current evidence.
