# a sodoku/magic-square-like cardgame, bamboozle

Played on a 5X5 grid:

XXXXX

XXXXX

XXXXX

XXXXX

XXXXX

Grid initially empty. The deck is made of the numbered spades and

diamonds (and aces) from two decks. Spades count positive their

value, and diamonds count negative their value. Aces count as +/- 1.

Two jokers can be used as well, if used, they count as 0. We've

enjoyed playing with 3 players, but play with 2 or 4 would be similar.

All the cards are dealt out to the players. Then players take turns

placing cards into the grid. At no time can the sum of values in

any row, column, or major diagonal be greater than 15 or less than

-15. A player scores a point if the row is filled and at the same

time brought to a sum of 15, -15, or 0. A row can not be filled

if doing so would bring it to some other sum. If two copies

of one card (e.g. two 7-spades) appear in one row, they count

together for the same value as one copy would (e.g. in this

case, +7). If you can't play, you must pass (obviously).

Most points after n iterations of these hands wins.

There are many obvious variations -- happy hacking.

(Invented by me and Kyle Schalm. Maybe there are other

similar card games out there already?)

We initially played by those rules. They are fun

too. I guess I shouldn't have said "obvious" because

there are so many possible variations.

No, a "hand" is the same as a "board" -- you redeal

after each round. At least, that was the way we were playing.

15 is the important number for Cribbage, so people are already

used to adding up to 15. You could certainly choose other numbers.

Maybe this would be another good example of a feature entry?

Two comments:

> If you can't play, you must pass (obviously).

Eh, I'd say not so obvious. You could lose the game right there (which would make, I think, for a much more aggressive game) or you could have to pass *and* lose a point.

> Most points after n iterations of these hands wins.

Do you mean with the same starting hands? Isn't this a pain to remember at the end of the hand?

Seems fun, though. I'll give it a shot next time an opportunity arises. Any reason you chose 15?
