Castle & Critter

Build Your Castle. Power It. Race It. Smash It. Now with Heat & Water!

What happens when you put a medieval castle on wheels?

You get a castle racer powered by animals.

Build your own ridiculous mobile fortress, place animals inside to power your wheels, manage your critter heat and water supplies, choose your armour and weapons, then race across dangerous roads against rival castles.

🏰 BUILD YOUR CASTLE

Your castle is built on a grid, and every piece takes up real space. Progress through six distinct castle hulls—from the Wooden Keep all the way up to the gothic mini-city Royal Palace.

Choose what matters most:

• 37 animals, from hedgehogs up to the majestic Griffin, to power your wheels
• Four gear boxes and the new manual SHIFT UP / SHIFT DOWN controls
• Walls and armour for protection
• Water systems (ranging from Water Buckets to Grand Water Towers) to cool your overheating critters
• Rams for devastating impacts
• Archers, crossbowmen and guards
• Ballistas, catapults and trebuchets
• Food and fuel to keep your animals powered and supplied

Every build is a compromise. Want a massive rolling cathedral? You’ll need to master the grid, manage your weight, and keep your engines cool.

🔥 CRITTER HEAT & THE WATER SYSTEM

Forget simple stamina. Your hardworking animals now generate heat as you drive:

• The heat meter runs FRESH → TIRED → FATIGUED → EXHAUSTED → COLLAPSED.
• A total collapse stops your castle dead in its tracks and fails the mission.
• Use the new Water System to cool your critters from anywhere in the castle, and rely on an Emergency Soak to save your run right before a collapse.

🛞 TAPPABLE DRIVE & RACES

Take your castle onto the road and race through dangerous environments:

• Tap-to-Drive: Tap the throttle instead of holding it, and tap fast to trigger a high-speed overdrive! (A "Hold to Drive" toggle is also available in Settings).
• Avoid obstacles, survive enemy attacks, and outpace faster rival lords who now sport their own hulls and custom flags.

⚔️ DEFEND & 💥 SMASH THE CASTLE

Your enemies aren't going to sit around and let you pass. Defend your rolling fortress with elite troops and siege weapons, then reach the end of the road to face the enemy fortress:

Castle Mass×Impact Speed×Ram Power=DESTRUCTION

Watch walls crack, towers shake, and enemy gates collapse under the impact.

⭐ CONQUER THE KINGDOM

• Master 100 missions across 10 biomes.
• Face Lord battles every 10th mission and smash through 150 unique end-of-road targets.
• Earn gems for perfect runs and destroying enemy Lords' castles, then spend them in the new Gem Store on exclusive castle skins, special animal breeds, hats, and rare horseshoes.
• Complete the campaign, earn a permanent crown, and test your skills on harder runs with faster rivals and denser enemy formations.

🏆 BUILD IT. RACE IT. SMASH IT. There is no perfect castle. There is only the castle you built. How will you build yours?
