Here's the "informative" video for the Thumb Stadium solder kit:

Standard Games:

Game 1 ~ ThumbWar™

The object of ThumbWar is simple: press while the other player is pressing. If you do, you get a point.

Game 2 ~ SlapJack™ During SlapJack, Thumb Stadium randomly flashes the center LED red or green. Be the first to press when center is green and get a point. Don't press if it isn't green or the other player gets a point.
Game 3 ~ Jai Alai™ Center lights up ~ quickly press to "catch" your color. Press again to "throw" to the other player who has to catch on time and throw back. The time to catch gets shorter each throw.
Game 4 ~ Reflexy™ Reflexy is a one-player game. The object is to quickly press the button that matches the color in the center LED. You go until you miss or are too late. The time to react gets shorter each turn. After the game, your score is flashed ~ Center = x10, Red LED = x1. Press the Red Side Button three times to restart.


To use the Thumb Stadium Solder Kit, turn Thumb Stadium on with the slide switch. The LEDs will alternately flash green then red while ThumbStadium waits for you to press the Green Side Button. After the first press, the green player LED will flash indicating Game 1 is selected. Pressing the Green Side Button again flashes the red center LED indicating Game 2 is selected. Another press selects Game 3 and flashes the green center LED. One more press and the red player LED flashes indicating Game 4. Additional presses repeat this cycle. Choose your game by pressing the Red Side Button.

In the 2-player games, the first to 5 wins. Because rematches are at the sole discretion of the victor, only the winner can restart the game by pressing 3 times.




Thumb Stadium Game Chip 2 ~ TS-2

Game Chip 2 video:

Game Chip 2 ~ TS-2 games:

Game 1 ~ Hot Potato™

Hot Potato tests your reflexes in a whole new way. Everyone is used to pressing a button quickly, but how fast are you at letting go! Stop being so co-dependent. The center LED flashes red until both players are holding their buttons down, then pulses green for 2 seconds until becoming solid green. The potato stays green for a random amount of time then suddenly turns red. The first one to let go gets a point, the other player gets burned! Make sure you are holding onto the game with your other hand so you don't drop it! Play alone to see if your left or right brain is faster...doh

Game 2 ~ LED Tennis™

LED Tennis takes the classic video table tennis to a whole new binary dimension! The center LED lights up in a random color, stays on for a bit, then the corresponding player LED is lit. While your player LED is lit, you need to press to return the volley at which time the ball changes direction. The volley accelerates rapidly until someone misses by pressing at the wrong time. The next serve goes to the player who missed.

Game 3 ~ H-O-R-S-E™

Just like the basketball game. The first player programs a pattern of red and green button presses. The second player gets to play it back twice then has to copy the pattern. If he gets it right, it's his turn to put in a pattern. If he misses, the first player needs to duplicate the original pattern. If he can, he gets a point. If he makes a mistake the other player gets a point and it becomes his turn to put in a pattern.

Game 4 ~ Look Over Here!™

Select Game 4 and get treated to a spellbinding Light Show! Sure to get anyone's attention. Try it at your favorite restaurant to call your waiter! Leave it running on your dash to deter thieves, unless they love binary LED games! Meet your future spouse! It's magical! It's like having the Las Vegas Strip in the palm of your hand!!!
