this happened to me, my friend was playing on my old real feal, and he was done and jokingly threw it at me, i didnt think he would but it landed right on one of the corners, and there was a massive chunk missing but anyways,

i took the pad made a boarder around the broken part with tape, and filled it with wood glue, it took like a week to dry completely, but when it was done i just colored it with sharpie, and it looks pretty good.
ill post pics later
