Flat ground only, but, that does not mean anything on flat ground counts. No feet on the ground. That means no "No Comply's", no "Hand plants", no "Bonelesses", and no grabs. No doing tricks that slide on the ground if your opponent popped it. Last letter gets two tries. Offensive toe drag gets one do over. Defensive toe drag has a bigger margin of error but will ultimately be decided by the referee. If trick maker does not pop the trick but is still landed, the trick still counts.
