UPDATE:As reported by an user on the comment, the game is free until level 5.
CastleStorm is coming to mobile devices on May 8th! The mobile adaption is free to play and offers a lot of content and features.
Featuring console quality graphics and controls tailored for the touch screen, CastleStorm – Free to Siege includes four full campaigns with 150 battles and four nations with distinct troop classes, weapons, spells, bonus rooms, eight playable hero characters as well as brand new spells for the mobile version!
only to lvl 5 is it free to play after this you must pay real money.
Good to know thanks.
