    It's not my homework and it's nothing to do with computers. I just need an idea and I need it in the next four hours! My eldest daughter is making a game for a school project. We've done most of it (actually I did the layout for her and she coloured it in). We've made lots of pretty counters and we know how the game will work. Even my three year old monster-angel (tm) understands. Now for the problem... We've been using dice, but (i) I'm not overly happy about it and (ii) I don't want her take the few dice we have to school and loose them. I thought I could find a few dice in one of the shops. Not on your Aunt Nelly's Life! So any ideas guys? Something a six year-old can make and use that will allow a bit of chance in travelling around what is basically a simple maze.

    Use 6 pennies. Have the kids shake them in a cup, and pour them on a table. Count the number of heads.

      How about a "spinner"? a hexagonal peice of card with something along the lines of a toothpick or small pencil through the middle (taking appropriate health and safety precautions!), each side represents a number 1-6, give it a spin and whichever side it comes to rest on dictates the next move. It will give her a bit more colouring in to do too!

      How did you come up with that idea I wonder?

            Here's a youtube vid on making them out of folded paper, but the pennies idea is good too. Hope there aren't any other greedy kids... http://www.youtube.com/watch?v=SWAIFCraUvo I'm sure you could find other die types if your game required, say, a dodecahedron (12 sided die, but that's only used for rolling damage on a Greataxe). By the way, you don't have to make excuses for needing a D&D fix, and your wife threw out all your dice. I came "out of the dungeon" some years ago. It's liberating to say out loud "I'm a Dungeon Master and I'm fine with that!" or "I enjoy playing my level 16 half-elf ranger!" Wait... I think my wife is coming upstairs... gotta go. Hope that helps! Scott P

              It's been a while since I did any statistics, but does 6 pennies in a cup provide an even distribution? :^) I thought it would lean more heavily towards the middle numbers (3 and 4 or whatever). Of course, this is a kids' game, so it might not matter...

                There are more solutions in the problem space that provide a central result (e.g. only one zero and one 6 - hhhhhh and tttttt) whereas you'll have around 1/3 of your distribution around '3' and about 1/4 for each of '2' and '4'.

                It definitely isn't definatley

                  I believe 6 pennies matches the behavior of a single die, at least sufficiently for the purposes of a kid's game.

                    Find yourself a D&D/ board game shop. Those usually have bins of loose dice you can buy dirt cheap. Send her to school with 20. If she comes back with 3 call it a win.

                      I understand the problem right, we need to find a substitute for throwing a dice. Probability of getting each one number on a dice is 1/6 ... one out of six ... something like 16.6% But when you throw six pennies, you have to use different formula for probability. That is: P(x) = (n above x) × p^x × (1-p)^(n-x), where n is number of pennies ... in our case 6, x is number of favorable events ... heads in our case, and p is probability of one favorable event ... in our case, heads or tails, 0.5 long story short :) Probability of getting 1 is 0,09375 Probability of getting 2 is 0,234375 Probability of getting 3 is 0,3125 Probability of getting 4 is 0,234375 Probability of getting 5 is 0,09375 Probability of getting 6 is 0,015625 Plus, there is probability of 0.015625 of getting 0

                        Not even close to a regular die. Odds: 0 = 1/64 1 = 6/64 2 = 15/64 3 = 20/64 4 = 15/64 5 = 6/64 6 = 1/64

                          Just use a pencil. I don't know about your area, but where I'm from, most of the pencils are hexagonal. So you just write numbers 1 - 6 on each side and throw the pencil.

                              You've got to consider the audience here. This is for a kid's game. That means you've got to be able to explain how it works and the rules to a kid. KISS: Keep It Simple, Stupid. I doubt it matters that the distribution is not the same as with a regular die. Come to think of it, it does not matter. As long as the probability of each player getting the value of a particular 'roll' is the same as every other player's probability of getting that same roll, then the gameplay is fair.

                                  You're kidding, right? You can get a box of dice at your local discount store for almost nothing--certainly for less than the effort it would take to come up with some lame work around.

                                    As long as we're being pedantic here (and we are), I stated: "I believe 6 pennies matches the behavior of a single die, at least sufficiently for the purposes of a kid's game." The behavior in question is that of somewhat randomly choosing a value from one to six (I'll admit I missed the zero case), which is what matters as far as the game is concerned. The part of the statement in bold qualifies the first part.

It will give her a bit more colouring in to do too!

                                      Very clever! :-D I was going to suggest something involving a chunk of cheese and a small rodent...

                                        As long as we're being pedantic here (and we are), I stated: "I believe 6 pennies matches the behavior of a single die, at least sufficiently for the purposes of a kid's game." The behavior in question is that of somewhat randomly choosing a value from one to six (I'll admit I missed the zero case), which is what matters as far as the game is concerned. The part of the statement in bold qualifies the first part.

                                        Of course we are. Do we do anything else around here ;P

                                          It's not my homework and it's nothing to do with computers. I just need an idea and I need it in the next four hours! My eldest daughter is making a game for a school project. We've done most of it (actually I did the layout for her and she coloured it in). We've made lots of pretty counters and we know how the game will work. Even my three year old monster-angel (tm) understands. Now for the problem... We've been using dice, but (i) I'm not overly happy about it and (ii) I don't want her take the few dice we have to school and loose them. I thought I could find a few dice in one of the shops. Not on your Aunt Nelly's Life! So any ideas guys? Something a six year-old can make and use that will allow a bit of chance in travelling around what is basically a simple maze.


                                          Panic, Chaos, Destruction. My work here is done.

                                          I see a recurring problem here - your eldest isn't making a game for hte school project - you are (although you seem to have let her do some painting - good on ya!) I'd be surprised if there aren't dice at school - kids will be familiar with dice from otgher games, so otehr forms of numerical randomisers can actually be less simple to them than using a dice - and if she takles tehm in and leaves them at school - buy some more! If you really don't want dice, other options are spinners (like a clock - number roundthe outside, some form of spinning pointer in the middle) but is hard for a 6 year old to fashion on that spins well, hexaganol spinners (much easier to make although you'd need to draw the hexagon - but hell, you done the rest of it :) you can use a short pencil for the axis. You can also use a sheet of paper, with large squares (or any shapes) drawn on, each with a number in. Roll a coin, or even a screwed up piece of paper, onto the sheet, and the number it lands on is the number - this does tend to be skill-driven though - and in my experience kids will try to cheat. Draw straws. Take however many straws (or strips of card) and write a number on one end - put them in a tub and draw on out - use the number. For younger kids (they see through it at six) you can use the 'daddies hand' method. Clench a fist, they tap your hand three times (one, two THREE!) and you open a number of fingers. That's all my ideas done for the day, and its only 8:00!

                                          If I knew then what I know today, then I'd know the same now as I did then - then what would be the point? .\\axxx (That's an 'M')
