In the 16 ring game, each ring is equal. Over time you will lose tickets. This game is a better bet for the unlucky title because you will lose less with each game than 9-ring and you'll increase your unlucky title for less money.
9 Ring is much faster however at increasing your lucky title, but it costs more gold per hour than the other game. If you want the unlucky title as well, the corner rings are a better bet, but overall each ring averages out to the same cost per game.
These calculations are based on pure math theory and they assume a perfect random number generator (RNG). In reality there is no such thing as a perfect compterized RNG. So, here's my question: Has anyone here done any analysis on the RNG used in the ring games? Any noticable flaws popping up that tend to favor a ring? I'm assuming that since most of GW is based on "dice rolling" combat damage that they have a fairly decent RNG developed, but I can always hope.
