From Back Cover: "Tons of stone slowly descend as you frantically search for the answer to a simple riddle. Dozens of razor sharp spikes cut your time even shorter. Solve the riddle and the treasure is yours. Otherwise... The Adventurers on the cover have solved it, can you? RiddleRooms #1 Dungeon Dilemmas contains twenty illustrated rooms, each posing a riddle or challenge. Some are deceptively simple: others are fiendishly complex. Riddle Rooms can be used with any fantasy role-playing system -- this is not a dungeon module. The rooms are designed for you to add to your dungeon. Treasures, traps and damages are suggested but the final decision is always yours. Included are: Den of the Devourer The Impervious Cube The Greenhouse Effect Hall of Flames Perfect Harmony Lair of the Swarm The Hidden Tomb Wizard's Workshop Doorways to Danger and ten other rooms to challenge you and your players. Also included are five bonus riddles for you to use in making your own Riddle Rooms and a special Riddle Item - The Perilous Potion." 2nd Edition
