🟢

Apprentice

5 hearts · slower timers · multiple choice & true/false only · questions gently favor elements you're still learning. Learn the ropes of the dungeon.

🔵

Scholar

4 hearts · brisk timers · some questions must be typed · bosses punish hesitation. The intended way to play.

🔴

Archmage

3 hearts · merciless timers · packs of tougher monsters · mostly typing. For masters of the table.

Descend through 7 dungeon floors — one per period of the periodic table. Explore, fight monsters with your chemistry knowledge, loot chests, crack 🔐 vaults with keys from elite kills, collect relics, and defeat the boss guarding each staircase — every guardian fights differently. Reach the bottom to win… then, if you dare, keep going: the 🕳️ endless Abyss waits below Floor 7.
