You are participating in multiple games involving two slot machines, labeled I and X.
The two slot machines are different in different games.
Each time you choose a slot machine, you get points (choosing the same slot machine will not always give you the same points).
You select a slot machine by pressing the corresponding key.
The expected points change randomly, abruptly, and independently with a hazard rate (which you will be told).
When the points change, the new expected point value assigned to that slot machine is sampled from a uniform distribution (from 1 to 99 points).
For example, if the hazard rate is 0.1, the expected points of the machines change with 10%.
Your goal is to choose the slot machine that will give you the most points.

Game 1. The hazard rate is 0.2. There are 100 trials in this game.
