I have found 5 different overlays for "Las Vegas Poker & Blackjack", but basically there are 3 versions.  They all have the same i.d. number, with some slight differences. They are distinguished by their arrow colors, or tints.

 *(Right) -  In the (error) version, the text "card", next to the # 1 button on the keypad, is missing. There are very few of these in circulation. See it to the right, next to a regular version Poker overlay.

*(Below) - The Yellow text version was the first to be produced. The whole overlay is much lighter than the other two. It was in this version that the (error) Yellow overlay was produced.

*(Below) - The (Orange) text version seems to show up from time to time, with the (Red) text version being the most common.  Look at the 3 different overlays next to each other below.

 The last variant overlay I am currently aware of  for the Poker game is made by (Digiplay). This overlay has been re-produced by Digiplay in South America. The overlay is printed in Brazilian Portuguese.
