Prerequisite: Familiarity with the digits 0 to 9 and the ability to perform addition of two digits. Preferably, the players should be able to distinguish between ones-digit and tens-digit and be also familiar with the numbers from 1 through 100.

Ages: 7 and up.

Participants: 2 to 6 players.

Cards in game: All numerical cards; inclusion of any of the “free” cards

() and inclusion of the “100” card, are optional.

Object of the game: To discard all cards in a player’s hand.

Set-up: Same as games 1 and 2.

Basic rules of play:Like in games 1 and 2, except basic rule 1 - each player in turn may discard

up to 3 cards, provided each card matches the previously discarded card by:

a. |
A common ones-digit; OR |

b. |
A common tens-digit; OR |

c. |
A common sum of digits. |

For example, upon the card “23” the player may discard any card with a ones-digit=3 (i.e. “3”, “13” … “93”),

or a tens-digit=2 (i.e. “20”, “21” … “29”),

or a sum of digits = 2+3 = 5 (i.e. “5”, “14” … “50”).

Therefore, upon the card “23” the player may discard “27” (common tens-digit=2), may keep his turn and discard “57” upon the “27” (common ones-digit=7) and discard “66” upon the “57” (common sum of digits=12), i.e. discard the sequence “27”»“57”»“66”.

Note: The “

Sum of Digits” card might be useful.

Special cards rules:
1. |
A player ending his turn by discarding a Monumeral () obliges the following player to choose one of two options:
a. |
Discard only a Monumeral, thus obliging the next player, and so on; or |
b. |
Lose a turn and draw three extra cards from the draw pile, and then the next player is free to continue the game according to the basic rules of play. |
For example, upon the card “23” player A discarded the sequence “53”»“59”»“9”, player B discarded “7” and player C had to draw 3 cards from the draw pile because he did not discard a Monumeral. Now, upon the “7” player D may discard up to 3 cards according to the basic rules of play. |

2. |
A player discarding a Twinumeral () may successively discard upon it all cards with this same digit, by order of his choice (even more than 3 cards). For example, upon the card “23” a player discarding the sequence “27”»“57”»“66” may keep his turn and discard upon it all cards with the digit 6. |

3. |
“Free” cards () are used as in game 2. |

4. |
The “100” card () is used as in game 2. |

End of game: Same as games 1 and 2.
