13 cards can be arranged in over 6 Billion possible combinations ... 6,227,020,800 to be exact. A version of this game is said to have been found at a UFO site in Texas back in the 1980s. With its mysterious origin, we are still unclear as to the strange effects of achieving the "13" result. Some say it sharpens intuition, improves focus, and intelligence.
But who knows....
Mix the 13 cards and place them in a 5-3-5 configuration. Two cards will be removed on every turn, can you remain with only one card in the end, preferably the 13!
