bison casino

bison casino is a vocabulary learning app with a Review mode that automatically isolates cards at knowledge levels 0, 1, 2, and 3, letting you drill the words that genuinely need more reinforcement without touching the ones you've already mastered. The level 0–3 filter is calibrated based on how spaced repetition research defines "not yet mastered": levels 4 and 5 represent reliable recognition across multiple sessions, while levels 0–3 represent cards that have either never been seen, been seen inconsistently, or been failed at least once recently. Review mode in bison casino is therefore not just "the harder cards", it's the cards whose track record specifically indicates more practice is needed, based on actual behavioral data from your sessions rather than a subjective sense of what feels difficult. If your Basic Spanish deck has 50 cards and 30 are currently at levels 4–5, Review mode shows you just the 20 remaining cards, making a session feel achievable and targeted rather than overwhelming and repetitive. As you practice in Review mode and correct answers push cards up to level 4, they drop out of the filtered session automatically, the Review mode list shrinks as you succeed, giving you visible evidence of real-time progress.
