FitGoblin turns everyday movement into an RPG-inspired fitness adventure. Complete activities, develop your goblin’s attributes, earn rewards, collect powerful equipment, and battle fearsome bosses. CHOOSE YOUR PATH Select your main activity and up to two side activities. Track workouts with the live timer or add completed activities manually to your history. Earn Gems based on your level and chosen activity path. BUILD YOUR ATTRIBUTES Develop Strength, Stamina, Endurance, Agility, Mobility, and Discipline. Monitor Recovery, hydration, tiredness, steps, calories, and overall progress. COMPLETE QUESTS AND CHALLENGES Take on daily and weekly quests, unlock achievements, complete long-term challenges, earn XP and Gems, and level up your goblin. New challenges provide even more goals to pursue. COLLECT EQUIPMENT Discover weapons, armor, rings, and amulets. Equip items to improve your attributes and increase your damage against monthly bosses. UNLOCK LEGENDARY HERO SETS Collect the legendary armor and weapons of Odysseus, Spartacus, and Ragnar Lothbrok. Each piece provides a powerful attribute bonus, while completing an entire hero set unlocks an additional bonus for every item in that set. ENTER DAILY BATTLES Play a once-per-day match puzzle battle. Match attribute, sword, and Gem tokens, defeat your opponent, and claim permanent rewards. FACE MONTHLY BOSSES Every completed qualifying activity damages the current boss. Choose activities that match its weaknesses, avoid its resistances, and defeat it before the month ends.
