The game board features hexagonal tiles for scrolls to stand on, separated in two to distinguish each side. Unit placement is fairly crucial in a typical game of Scrolls, since units only attack in a straight line; default unit movement of 1 tile per turn helps alleviate this concern.
Both players have five idols on their side, with 10 HP each, which represent their health. A standard game of Scrolls is won by destroying three of the opposing players' idols.
Each player has 15 available tiles to place their scrolls, and can thus have a maximum number of 15 scrolls in-game at the same time; however, spells and enchantments can still be used after all spaces are full.
Units attack in a set order. The order is from front to back, from top to bottom. Therefore a unit placed at the top row and the front column (furthest away from your idols) will attack first when its countdown reaches zero.
It's unclear whether the type of terrain the scrolls are on will play a role in the first version of the game but currently they have no effect on gameplay.
