How do you select a prize from the arcade game stackers?

You don't "select" a prize in Stackers. Instead, you earn tickets by playing the game.

Here's how it works:

1. Play the Game: You play the Stackers game, trying to stack blocks as high as possible without making them fall.

2. Earn Tickets: Based on your performance, you'll earn tickets. The higher you stack, the more tickets you get.

3. Redeem Tickets: Once you have enough tickets, you go to the prize counter and redeem your tickets for a prize. The prizes are typically arranged based on the number of tickets required, with higher-value prizes needing more tickets.

So, in short, you don't choose a prize in Stackers, you earn it with your game performance.
