About this app

Win is a vocabulary learning app that respects the time you've invested in mastering cards by reducing their appearance frequency once they reach knowledge level 5, keeping sessions focused on what still needs work.

Reaching level 5 is a meaningful milestone: it means you've correctly recognized a card consistently across multiple sessions, and DraftKings's algorithm trusts that this word is now genuinely part of your vocabulary. These cards step aside to make room for lower-level cards that need more attention.

This behavior prevents the frustration that many learners feel in other apps, spending session time on words they already know perfectly while struggling words don't get enough practice. DraftKings's level-5 retirement keeps the difficulty calibrated to your actual gaps.

Level-5 cards don't disappear entirely; they reappear at longer intervals for maintenance review, ensuring that mastered vocabulary stays accessible even as new words demand more immediate attention.

The progression from level 0 to level 5 for each card creates a satisfying arc in DraftKings: a word moves from completely unknown to an occasional visitor that barely costs you session time, a tangible record of genuine learning.
