A formation tug-of-war
Buy a standing army. Every cycle it marches the dune. Hold the ridge, vent when you are ahead, and break the other citadel.
New here? A short first march will walk you through the table.
1v1, 2v2, or 3v3 against opponents that only see the waves on the field. Your lane leaks into the others when it is clear.
iPad silent switch does not mute this game. Use Mute here or on the field.
