9 Till Void is played on a 9x9 grid, where each row correlates with one of your spell slots. You can only cast a spell if your character occupies the same row on the board as the spell, so your position always matters.
Buy new spells to become more powerful! Where you choose to place your spell is just as important as what spell you choose to buy! Choosing which spell slot to replace is important, because you'll only be able to cast that spell from that row!


If you'd rather have more control over your spells, custom mode allows you to start runs from any of the 5 locations with pre-chosen spells. Custom mode is perfect for test driving spell combinations without having to hope for perfect RNG.
