New known high is 399.426 since the Cowboy found the solution for 998 in level 173 and me the 998 in level 364
I would never have thought 399,438 would be possible - and I won't be surprised to see some more turn up. But it still doesn't chance the fact that the top two people on the leaderboard are hackers. After all, there is no way to get 999 point on every level, especially when there are as many as 7 objects. And their scores were earned back when you couldn't get 999 on any level.
If I counted things correctly, I should point out that 29 of those points were only available on the old, pre-64 bit version of the game. And two of those 29 points ALSO had to have a certain iPhone to play it on. So, for anyone who didn't start years ago on old devices, the present highest score would be 399,421. But that doesn't need to stop people from getting darn close to the top score since you are presently second (of the non-hacker scores) and you didn't have those advantages. Cowboy had some of the advantages back then, though he didn't get all those special points. So he's only short 20 of them, rather than 29. If you remove that factor, you actually would have had 2 points more than Cowboy at this point. So, in a sense, you both have bragging rights to being the best!!! And since I got all of those old points, removing that factor would drop my score by 29. Still good for 3rd place though.
Looking like we must be very close to the maximal points possible. It's been at 399,463 for awhile now. There are theoretical improvements possible - levels with X number of objects that have not reached the best possible for that many objects. But most of those probably have issues requiring delays in drops to work. So, I expect more points will be coming, but maybe not a lot more.
