Clash of Skulls

Undead banners crowd the horizon. The fortress war in Clash of Skulls pits your tower against skeleton armies marching to smash the walls. After you enter your name, the battlefield fills with troops drawn from ranged fighters, melee ranks, spell users, siege crews, mounted attackers, and dragons that spit fire straight through the line. Wins bring back resources for upgrades. New battles hit harder than the last.

How to play?

At the bottom edge, unit cards unlock once your energy pool reaches the required amount. Drag a card onto the field, and that soldier or beast moves out toward the enemy citadel. When battle rewards come in, spend them on stronger attacks and sturdier units. Later rounds send heavier pressure, so mix cheap defenders with costly attackers before the undead reach your garrison.
