Choose the next upgrade from the options visible in your session. Compare current cost per observed gain, separate temporary boosts, and avoid claiming that luck maps to exact drop odds.
There is no verified universal “luck first” or “coins first” order. Pick one immediate goal, compare two upgrades in the same gain unit, and buy the option with the better weighted efficiency for the values you entered. Reset temporary boosts before measuring a baseline and repeat the comparison after each purchase.
Decide whether the next purchase is meant to improve observed cash speed, support a collection chase, or prepare a flexible World 2 reserve. Do not compare labels alone. A gain that helps cash can be valuable even when it does not claim to raise exact rare-item odds.
For each of two options, write down the price and the gain shown in the same unit. If the game presents unlike units, keep the comparisons separate or use a personal weight explicitly. The site cannot prove that one luck point equals a particular amount of cash or a specific odds change.
Potions, VIP benefits and server-wide bonuses appear in current player language, but their versioned effects and stacking rules are not confirmed. If a temporary effect is active, measure that state separately. Never treat a boosted observation as the permanent output of an upgrade.
The calculator divides current cost by observed gain and also compares observed gain multiplied by your goal weight, divided by cost. Lower cost per gain and higher weighted efficiency indicate the better numeric option for those inputs. The calculation is exact arithmetic; the inputs remain your observations.
Upgrade prices and returns can move after a purchase. A result for one level is not a full progression table. Re-enter the new costs and gains, then decide whether the next purchase still supports the same goal or whether saving cash is more useful.
Do not force a direct ratio. Compare each upgrade within its own unit or apply a clearly personal goal weight instead of inventing a conversion.
Enter the new costs and gains. The calculator describes the current choice, not a permanent progression table.
Cash per minute, luck points and a sale multiplier do not have a verified common conversion. Use separate comparisons.
Temporary effects can inflate observed gains. Record baseline and boosted sessions independently.
The tool compares the numbers entered. Random loot and hidden mechanics can make real results vary.
Compare the current price and visible same-unit gain for the choices in your session. There is no verified universal order for every goal and level.
The official description connects being luckier with better loot, but no complete formula supports a guaranteed result or exact odds conversion.
A weight is your preference, not a game coefficient. Keep both at 1 for a neutral comparison, or change one only when that type of progress matters more to you.
Measure boosted and normal conditions separately until the current effect and stacking rules are reliably documented.
