About
Pixel Keep Tower Defense is a pixel art survival tower defence game where you protect your keep from endless waves of monsters. Build Archers, Cannons, Frost Spires and more beside the road, upgrade them all the way to Elite and keep every slime, knight, bat and golem away from your walls. A boss arrives every ten waves, and every ten waves you survive earns a star on that level. Collect stars to unlock 13 levels, from a quiet meadow to snowfields, swamps, caverns and a volcano, each with its own road layout and foes. Every run earns crystals to spend in the Armoury on permanent upgrades, new towers and spells, so each attempt takes you further. Your stars, crystals and upgrades save automatically in your browser.
How to Play
Pick a tower from the panel, then tap or click an open spot beside the road to build it. Towers attack foes in range on their own; tap a tower to upgrade it, change who it targets or sell it. Press the wave button (or Space) to send the next wave, and call waves early for bonus gold. Gold comes from defeated foes and cleared waves, so spend it on new towers and upgrades as the waves get tougher. Each foe that reaches the keep knocks off some of its health, and the run ends when the keep falls. After a run, visit the Armoury to spend your crystals on permanent upgrades and unlock new towers and the Meteor Strike, Frost Nova and War Cry spells. On a keyboard, number keys pick towers, U upgrades the selected tower, F changes the game speed, E shows the foes on this level and P pauses.

Tips
- Build towers where the road bends so foes stay in range for longer.
- Knights shrug off arrows. Tesla Coils ignore armour completely.
- Bats fly straight at the keep. Archers, Frost Spires, Tesla Coils and Ballistae can hit them.
- Kill Shamans first or they heal everything around them.
- Salamanders are immune to fire, but frost hurts them badly.
- Golems have huge armour. Ballistae and Tesla Coils are the answer.
- Mega Slimes split when they die. Splash damage from Cannons cleans up the mess.
- Mortars cannot hit foes right beside them, so pair them with close defence.
- War Banners make a tight cluster of towers far stronger.
- Gold Mines pay out every wave, so build them early for the biggest return.
- The Treasury upgrade pays interest on gold you hold. Saving can beat spending.
- Tap a tower to change who it targets. Ballistae love the STRONG setting.
- Tap the enemy button at the top to see which foes are coming in the next wave.
Frequently Asked Questions
- How do I unlock new levels?
- Every ten waves you survive on a level earns a star there, up to ten stars per level. Your stars across all levels add up to unlock the next level, so going back to beat your best on earlier levels helps too.
- What are crystals for?
- You earn crystals for every wave you clear and every boss you defeat, with more on harder levels. Spend them in the Armoury on permanent upgrades, new towers and spells that stay with you for every future run.
- How do I lose?
- Each foe that reaches your keep damages it, and bosses hit much harder. When the keep’s health runs out the run ends, but you keep the crystals and stars you earned.
