Sach gets ahead of Whitey heading for the television, but in the next camera shot, it's Whitey who gets there first.

After Stone's death, all the spinning newspaper banners are printed with "Vol. XLIX, No. 1," even though days pass after the death and investigation. The number would have incremented each day.

In the gambling parlor, the cigarette girl's tray is completely empty, but she still says "cigars, cigarettes..."

It is never shown how nearly penniless Slip pays for the gambling lessons.

Bruce McDermott should have sued Gabe Moreno for slander in publicly naming him the operator of a crooked gambling establishment without proof. Gabe is an irresponsible journalist.

Slip and the boys work their way into the High Hat Club's gambling casino without telling Gabe, then they later decide to tell Gabe about it just as Gabe is beaten to a pulp by casino thugs. The criminals soon after learn of Gabe's connections to Slip and the boys and realize that's how Gabe has been getting inside information on their operation. This is impossible since (1) Gabe and the boys had no communications between them and (2) it isn't apparent what "inside information" Slip and the boys ever obtained.

To investigate the death of his boss, Slip and his boys take lessons in how to become masters at all forms of gambling, able to recognize and pull off any trick. Told in montage, this seems to have been done in a matter of hours rather than the much longer time needed to become "masters."
