You can play this game online on replit.
Move all the discs from tower 1 to tower 3.
There are three towers and five discs. Each disc has a size, ranging from 1 to \5. A smaller disc can stand on a larger disc, but not the other way around. That means you can place, e.g., a disc of size 1 on top of a disc of size 3, but not a disc of size 5 on top of a disc of size 2. You have to move all five discs on tower 1 to tower 3, using tower 2 as an intermediate to move them.
You'll be prompted to select a tower to take a disc from, or drop a disc onto. As you press any of 1, 2, or 3, your virtual hand will grab a disc from, or drop one on the selected tower. The game ends when all discs are on the third tower.
In case you want to quit, q is the input of choice.
