THE CLASSIC GAME The full Fitness 4 Fun experience, just like the physical deck. 2–8 players, solo vs. the computer, or pass-and-play with family. Match by number, color, or exercise — first to empty their hand wins.
THE CHALLENGE ARENA Quick-fire solo mode. Flip a real F4F card — the number × your difficulty = your reps. Beat the timer, build a streak, watch for action cards, and take on the Daily Gauntlet: the same 4 cards for every player, every day. Share your score card and dare your friends.
