Now there are more and more people like playing domino games, so just like marked cards with contact lenses for poker games, you also can use the luminous ink marked dominoes and UV invisible ink contact lenses to increase your winning odds in domino games.There are different type Dominoes and they can divide into Double-6, Double-9, Double-12 Dominoes.

In a double-six domino set, the numbers on the tiles range from 0 (or blank) to 6. In a double-six set, there are seven suits (blank, 1, 2, 3, 4, 5, 6), each with seven members. A double-six is the "heaviest" domino; a double-blank is the "lightest" domino value.

And each end of a double-nine domino tile, divided by a central line (or bar, divider, or centre), is marked with one of ten suits denominated as a number of spots (or pips) ranging from 0 (or blank) up to 9. Each of the ten suits has ten members with their spotted suit value marked on one end (or both ends for doubles) of the ten tiles that make up a suit. The total number of spots found on a Double-Nine domino set is 495.

While a double-twelve set contains 91 dominoes, with the numbers on the tiles ranging from 0 (or blank) to 12. In a double-twelve set, there are thirteen suits (blank, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12), each with thirteen members. A double-twelve is the "heaviest" domino; a double-blank is the "lightest" domino value.

A set of double-six dominoes is the most popular size of dominoes set. A double-six set allows you to play most of the traditional domino games. With 28 tiles, a double-six set is easier to manage than some of the larger sets, and takes up less space on a table-top.

Like marked poker cards, the regular dominoes also can be printed with the invisible marks on the back, the invisible marks can't be readable by naked eyes, only can be recognized from the UV invisible ink contact lenses or luminous ink glasses. When you play the game with luminous marked dominoes and invisible ink pen contact lenses, you will know the faces of dominoes in advance, so you can make the correct decision and control your game.
