Siege Clash

Siege Clash is a physics castle defence game where your hand is the main weapon. A horde marches on your castle wall, and you grab invaders and fling them into the sky, into each other, into the moat or into traps. Throw harder and they land harder; flick one sideways to bowl over a whole line like pins, or lift one high and slam it down.

The wall has help too: a Ballista and a Mangonel to fire, plus trapdoors, spiked rollers and tesla coils that trigger when you tap them at the right moment. Throwing enemies into the moat, lava or quicksand pays bonus gold. The campaign runs across 50 days and five worlds with five bosses, ending with the smug Baron Grimmholt and a volcano. Between days you upgrade the castle, recruit defenders and unlock abilities in the Keep.
