Taking Advantage Of Bias In Rock Paper Scissors

Here’s an infographic on how to improve you’re odds in Rock Paper Scissors. A year ago I linked to some research on bias in a coin toss (it’s not 50-50 it’s 51-49). At this rate I’ll eventually have an advantage in every game of chance.

Essentially this time around it’s more about psychology than bias in the implementation.

What’s the best way to prevent being gamed? Play rock, paper, scissor, lizard, spock, which has more possibilities and is just overall more enjoyable.

Very interesting stuff.

Google Pac-Man Hacking

Google Pac-man

Quick Hack

Here’s a literally 2 minute hack for the Google Pac-Man tribute on the homepage right now to put your own face on Pac-Man (pardon my poor photoshopping):

Pac-Man raccetturaized

To try it add the following bookmarklet to your browser by dragging the link below to your bookmark bar:
raccettura-ize pacman

Now go to Google and press “Insert Coin” to play the game. Once the game loads, run the bookmarklet by clicking on it.

Hack yourself into Pac-Man

Want to make your own? You likely have better photoshop skills than me. Download this image and replace the Pac-Man (and optionally Ms. Pac-Man) images with ones of your own keeping the position and sizes the same. Save as a PNG with transparency. Then upload somewhere. Now make a bookmarklet that looks like this (replacing URL_TO_YOUR_IMAGE with the url of your image):

javascript:(function(){document.getElementById('actor0').style['backgroundImage']="url('URL_TO_YOUR_IMAGE')";})()

Now share with your friends.

Google has now removed Pac-Man from the homepage but it can still be found here.
