If rock-paper-scissor is too simple for you, then you can try David Lovelace's RPS-15, with 1.3 trillion permutation and 105 possible outcomes. Still too simple, try RPS-25 with 15.5 octillion permutations and 300 outcomes. Link
Apparently, a bent dry spaghetti does not break in half but instead in three or more pieces.
After careful experiments, scientists discovered that ".. the mere release of the rod induces a stress increase. The multiple breaking of bent rods, like dry spaghetti pasta, can then be understood as a cascade of releases (loss of cohesion upon breakings) followed by stress increases leading to new cracks"
Still no cure for cancer. http://www.lmm.jussieu.fr/spaghetti/index.html
