Often played by people up to high school ,there’s this game which you may have seen. I’ve seen it described as a finite counting game :shrugs: but here goes
the one i was taught …15 dots, cross out 1, 2, or 3
whoever ends up with the last dot wins( OR, sometimes, loses)
Apparently, its a alt version of some ORIGINAL, nameless( DO YOU KNOW THE NAME???), game where peope take turns saying 1, 2,or 3 numbers, counting up till someone hits 20 for the winning number
Now, a long time ago , i figured out the strategy to the 15 version that i played. you’d want to leave your opponent with 11 , 7 , 3….
ack, my mind fails me, i forgot the strategy..
anyway,
1. is there a NAME to this game?
#2. someone i met said the strategy was that you were playing to get to a end number , N. Now, could you explain this for someone who is having a dum moment?
3. He was able to name any goal number, and figure out what to leave me at to lose. ). How’d this happen? for example, he did a game up to 90. . we could count up to 7. (of course i figrued out b4 we hit 20 that he was holding me at a set number every time i named a number, i think 6 or 2 numbers per round.
i found only one website(doesnt give me the name of the game_ , that has something on it, and mentions this, but it’s for going to a goal number of 20, and 21 , not 15. —–> http://riverbendmath.org/modules/Finite_Games
How can i get to the point so i can have someone name any number, and then KNOW how to set them up? At least i can tell when someone tries to play a rigged game against me, but i’d still like to master this.
K, new info that might help.
I found a old cheat sheet, with thison it-:::
For the game of 15 dots, crossing out one, two, or 3,
(always you go first)
if the goal is whoever gets the last dot LOSES , and you DONT want it, you leave the other guy with 1+4 , which meant 5, 9 , 13
if you WANTED the last ne, because whoever ended up with the last dot WON, it was 0+4 where you leave the other guy with 4,8,12
How does this relate, to the original finite counting game, and do the formulas i put on the cheat sheet …do they have anything to do with the remainder thing on that site i posted?
