Simon's Simulations

Simon's Simulations is a mini-game run by Simon in The Minish Cap. Located in Hyrule Town's central plaza, Simon will open his green, ghost-topped building to the public after Link has completed the Fortress of Winds.

Rules
After paying 10 Rupees to play, Link will be instructed to fall asleep in the bed provided by the shop. The young hero will "awaken" to find himself in a square, dungeon-like room filled with an assortment of monsters, including Moblins, Keatons, and Peahats. Link must destroy all of the monsters in order to receive a Piece of Heart, as a reward. Interestingly, in the event that Link dies in the simulation, he actually dies, instead of waking up, as one may expect. Link may return to play the mini-game at any time during his quest, however, the prizes range from Rupees to Recovery Hearts after subsequent, successful playthroughs.

Trivia

 * In the Dream Shrine from Link's Awakening, Link also falls asleep in a small room on a bed and awakens in a room filled with monsters.
 * The Take 'Em All On Game, also located in Hyrule Town in Spirit Tracks, resembles the Mysterious-Dungeon Simulation Game.
