Edge is a free knife-throw arcade game set in a shadowy saloon. A brass-rimmed wheel of dark mahogany spins before you — your job is to time each throw so your knife pins to an open arc without clipping a blade already stuck in the wood. Land all five knives cleanly to clear the round, then face a faster wheel with fresh obstacle knives and apple targets each time.
Throw with a click or tap anywhere on the board, the big THROW button, or the Space bar or Up arrow. From round four onward the obstacle knives snap onto a fixed five-point star 72 degrees apart, one more point filled each round until all five are in play, so the safe gaps become narrower and more regular — and from round five the wheel begins reversing direction every few seconds, which is where most runs end. Every fifth consecutive stick ignites Fire Mode: four seconds of bonus scoring worth an extra 100 points per knife, at the price of an immediate direction flip the moment it triggers.
