The Toronto Game

The Toronto Game is going to be a plot-based competition between teams to solve a series of puzzles that are based on the landscape and geography of Toronto. The organizers aim to make it fun, challenging, and intense. They plan to keep the game accessible to players of all skill levels, and also aim to provide participants with a very memorable experience.

For those of you familiar with ARGs and Puzzle Hunts, the Toronto Game is something similar. The primary distinguishing factors of this game are the emphasis on exploring public spaces, and the goal of accommodating casual players.
