Players drive slot cars through endless looping tracks in this casual single-player game. Users select cards to modify gameplay abilities and place gates on available track slots, where gate order determines maximum synergy output. Collecting charms increases passive score multipliers as numbers rise during runs that progress indefinitely. Synergies between cards create new effects while ghost cars spawn from specific card triggers. The Loopler relies on these mechanics to build scores. It is Steam Deck Verified.
