 867730.  Wed Nov 30, 2011 12:12 pm This is the game thread for Extreme Countdown. The rules are simple, you get the numbers 1, 2, 3, 4, 5 and 6, and may combine them using any standard functions to reach the target number. You may only use each number once, although you don't have to use all the numbers. For example, to make a target of 1,000,000, you would do (5x2)^6, completing the puzzle with three spare numbers. Scoring will be worked out as follows: Within 5% of the target number - 1 point Within 3% - 2 points Within 2% - 3 points Within 1% - 5 points Within 0.5% - 7 points Spot on - 10 points Two bonus points are awarded for each number left unused, if you successfully reach the target number. The first target number is 123,456. I'll post my best solution in a few days time :)

 920719.  Sat Jun 30, 2012 11:48 am Easy - 123456 = 123456. 10 points please. PS: Yes - you're missing something, wiz.
