Stampede is a video game cartridge which was released in 1981 for the Atari 2600 video game console, and the Intellivision video game console in 1982. The game is a left-to-right side-scroller with an overhead, third-person view. It was published by Activision.
An Activision catalog from 1982 advertised Stampede in the following way:
'Ready for a little round up? With Stampede by Activision, you'll have to ride fast and rope even faster. Those little dogies seem to be everywhere, and they're all worth points. But, be careful! Your ol' horse can get a little edgy, especially when you take your eyes off the trail. So, head out West for hours of fun with Stampede!'
The objective of Stampede is to round up all of the cattle you encounter. To do so, the player must lasso each one in order to capture it. The player is initially only allowed to let two cattle pass; if a third one slips by, the game is over.
An important caveat to this is that the player gets one extra free pass for every 1,000 points scored. So, if a player were at 2,000 points and had not yet let any cattle pass, then he or she would be allowed to let four cattle pass before the fifth one ended the game (assuming he or she did not reach 3,000).
This makes it possible for an expert player to repeatedly beat the game—as after about 5,000 points or so the game essentially 'resets,' and the same pattern is repeated. According to David Yancey, there is a bug which makes it so that the game will typically only allow you to play in a loop for 8 play throughs; apparently, however, there is a version of the game with a different binary which allows one to continue to accrue points until the score 99,999 is reached.
