I am having extreme difficulty finding dominoes less than 4.5cm x 2.5cm x 0.8cm in size. All stores seem to sell from the same manufacturer, which are too large. Can I grind down commercially made dominoes to meet the maximum size requirements?

Dominoes must be unaltered commercially manufactured and less than 6.0 cm x 3.0 cm x 1.0 cm. This increase in size is due to the difficulty of finding the smaller size dominoes in certain regions of the country.

Please clarify what constitutes a "competition violation."

Any rule violation that occurs during the actual operation time is considered a competition violation. If there is not a penalty assessed per section 8, it will result in tier 2 placement.
