You can play this game almost anyplace: with darts on a dartboard, lawn bowling (bocce) balls on a grass field, or even pebbles thrown onto the ground. Or any objects you choose thrown onto any sort of "field" you desire.

This is a game for 3 players. Each player gets 3, let's say beanbags. Players
takes turns throwing one beanbag onto the floor. The object is to "stake out" as large a triangle as you can with your beanbags, without having anyone else's beanbag be inside your triangle.

After all 9 beanbags have been thrown, any player who has an uninterrupted triangle earns points equal to the area of his triangle. (Use Hero's Formula to calculate the area of the triangle from the lengths of its sides. -- see below). Everyone else scores nothing. Players must decide if they should use their final beanbag to complete their triangle, spoil someone else's, or possibly find the magical spot on the field which would accomplish both -- if they can hit it!

Play 6 rounds, one round for each ordering of the three players. (i.e. 123, 132, 213, 231, 312, 321). Highest score after 6 rounds is the winner.

NOTE: Hero's Formula is: Area = SQRT [s (s-a) (s-b) (s-c) ] where s = (a + b + c)/2. Sides can be estimated (e.g. with footsteps), but be sure to bring a calculator.

NOTE 2:
In the beanbag or lawn bowling versions, there should be a line on the field that you have to throw your marker beyond in order for it to count. Otherwise you can place your markers too precisely, and that takes the randomness out of it.

I agree the math part would suck the fun out of this. How about a camera phone app that can measure the triangles automatically? If the beanbags were brightly colored, and each set different, it might not be too hard to implement.

Alternately, this could be an application for the EyeToy camera attachment to Sony's home game console.

BTW, I did play this game 15 years ago (I had to play all three sides by myself), and part of the fun was running into the computer room and typing the three lengths into my Apple IIe to see what the final area would be.

Seems somewhat interesting, especially considering that someone who can throw accurately could bust up someone else's triangle while scoring a good one of their own (it would also be possible for two or three people to score very large overlapping triangles).

//I had to play all three sides by myself// and //part of the fun was running into the computer room and typing the three lengths into my Apple IIe// I have rarely read anything sadder on the Halfbakery, so much so that I had a tear in my eye. In a completely non-sexual sense [phundug] ...do you need a hug? At least, take this spare bun.

Also, "Musical Triangles" - Three teams of three people run around, trying to maintain nice triangle shapes while avoiding having anyone else from one of the other teams in their triangle. When the music stops the triangles are judged according to [phundug]'s rules.

I would think it would be virtually impossible to complete an unspoiled triangle. There are twice as many against as for. By the sixth or seventh bag toss, maybe one of the three players might still have a shot at it remaining, and with the other two having no other goal left but to ruin that chance, will do just that.

//Players must decide if they should use their final beanbag to complete their triangle, spoil someone else's, or possibly find the magical spot on the field which would accomplish both//

How about if one "beanbag" of each players set had a laser measuring device in it and controller, and the other two bags have a receptor tuned to that particular controlling beanbag and their own lasers. The bags themselves then check first to see if there is an un-interrupted triangle, then measure and figure the area of that triangle if it exists.

I played Fluxx once and found it to be ill conceived, humorless, and dull. It might have been cute if the cards were all fun things like "cookies" and "milk". But once they stuck death and taxes in there, who wants to be bothered? I already have a job.

[waugs] - consider also that, in some incarnations of this game, it would require not just skill but chance to really get a token exactly where you wanted it. For example, playing on a golf course or with tiddlywinks. Or both. Even if a player wants to spoil anothers triangle, it's not necessarily given that they can.
