Gakumas Memory Skill Card Probability Calculator
Estimate the chance of getting a desired skill card combination in a memory. Compare target cards, acceptable alternatives, excluded cards, acquired cards, and produce rank before planning your next attempt.
Choose the cards you want under Target skill cards. Add acceptable alternatives with OR, or use NOT to exclude cards. Enter acquired cards, including their pre- and post-upgrade versions, then select the produce rank. Review the success and failure combinations. Draft pick lets you compare candidate cards before adding one to the acquired list.
The calculator enumerates combinations allowed by its memory cost model for the selected rank and sums the probabilities of outcomes matching your targets. Its uniform-distribution model is an estimate: the real skill card selection algorithm is unknown, so the displayed probability is not a verified in-game rate or a guarantee.
- How do OR and NOT change a target?
- OR accepts any one card in that target slot. Separate positive slots must all be satisfied by different cards. NOT excludes memories containing any card in the negated slot, including its alternatives.
- Why can success show 100%?
- Every outcome in the current model matches the selected targets. With no target or exclusion selected, every modeled outcome counts as success. Check that you entered the intended targets, acquired cards, and rank; 100% here does not prove the game's actual lottery odds.
- Are these the game's official probabilities?
- No. These are estimates that assume every memory is equally likely, as the note at the top of the calculator says, so actual outcomes may differ.
