Gold 500 Lives 10 Score 0 Best — Wave 1 / 10 Easy Normal Hard 1× 2× 3× Send wave 1

Upgrade all Remove all

Swordsman 85 melee · 5 Crossbowman 105 shooter · 3.5 Griffin 255 melee · 14 Lightweaver 290 shooter · 11 Cavalry 850 melee · 24 Inquisitor 1000 melee · 42 Angel 2400 shooter · 62.5

On a phone: tap a troop for its panel, drag it to move.

How to play

1. Pick a troop from the list and tap a free cell — it takes position there for the price shown.
2. Melee only reaches the neighbouring path cell, but hits twice as hard. Shooters cover three cells from anywhere.
3. You send each wave yourself — nothing moves until you do. Clicking your own troop opens a panel: upgrade it, or remove it at a full refund.
4. Every kill pays gold. Anything that reaches the gate costs a life, and you have ten.
5. The path changes before waves 4 and 7, then every five waves in endless defence. You see the new one before you send the wave.
6. A troop that ends up standing on the new path comes back to your hand, money included.
7. Every troop has an upgraded form taken from the game itself — its own name, price and stats. Upgrading costs less than fielding a second one.
8. A troop can be dragged to another cell with your finger — even mid-wave. But it spends a few seconds redeploying and holds its fire, and the pricier the troop the longer it takes: a Swordsman almost at once, an Angel four seconds.
9. Pick the difficulty before the first wave. On Easy the undead have half the health and move a bit slower, but you score half as much. On Hard they are tougher and a touch faster, and you score 1.5× as much.
10. “Upgrade all” upgrades troops while the gold lasts, cheapest upgrade first. “Remove all” clears the board for a full refund. It only works between waves — handy for rebuilding around a new path.
11. Hold ten waves and you can keep going in endless defence. The undead get tougher with every wave, and the game ends with your last life. Your lives bonus is locked in when you clear wave 10, so lives lost later won’t cut it.
