Excellent detective work on your part, @demoledorachang -- worthy of a 100% upvote.

The flaw you mentioned is, unfortunately, applicable to any Flash game that saves locally to players' hard drives using .SOL files. Not only could multiple users share the same computer to get similar scores, but the same effect could also be achieved by copying the .SOL file from one computer to another.

There were several rules in place at Arcade Boss during my original run to address this flaw and also to help maintain integrity and honesty in the competitions. The most important ones that I could recall were:

• If two people from the same household wanted to compete on the site, they had to use different computers (and there were ways even back then to detect this), and they could not both be logged in at the same time.
• If you knew of a glitch or exploit within a game that would allow you to produce a score that would otherwise seem impossible, you were expected to inform one of the appropriate moderators, with enough detail that the glitch or exploit could be reproduced. While glitching one's way to a high score was never encouraged, if you followed those steps then you were in the clear, as it was obvious that you did not cheat.
• Moderators could create and operate puppet accounts whose purpose would be to post impossible scores to try and catch a suspected cheater (almost always a hacker or a botter) in the act. These "puppet scores" were expected to be removed upon completion of the current investigation, so that those who earned their scores honestly could receive the appropriate recognition for doing so.

There were quite a few family pairs (spouses, parent-child, relatives, etc.) who played on Arcade Boss back then, and there were no scoring issues with any of them. It was understood that everyone was expected to put in their own individual effort on the games, and as far as I knew, all the family pairs honored this principle. In addition, although the site and its administration had both automated and manual means to enforce competition rules, it also relied heavily on the community of honest gamers, at all skill levels, to help maintain the integrity of the competitions.

Now since these retro tournaments are being run from Steemit and merely using Arcade Boss as the battleground, we have no automated means to enforce a "one person, one account, one computer" rule. And since Arcade Boss stopped prize competitions altogether back in 2016, there's no way the moderator or admin of that site could be bothered to do enforcement for us now.

What we do have now is a new generation and new community of Arcade Boss players, and it's up to us to collectively help ensure the integrity of whatever competitions are devised. And one good way to accomplish this is exactly the same thing as what the old-timers did: communicate. Know who the regulars and who the good gamers are. If you've got a question or see something that looks out of whack, ask. If you're asked a reasonable question, try to answer it to the best of your ability. You don't need to give away any secrets that you've figured out on your best games, but you should be prepared to explain how something could be theoretically possible -- e.g. you might say that a certain game mechanic or rule exists, but you don't have to tell someone how to use that mechanic or rule to get a really high score. (Want some examples of this? You can find plenty in the Arcade Boss forums if you search carefully.)

With all that being said, I see that @tonyxpin has explained his side of the story and he has also made good on correcting the issue that arose from this tournament. Based on his brief history in the tournaments, I am inclined to believe that what happened here was an honest mistake. Taking all this in consideration, I'm also going to give @tonyxpin a 100% upvote on his comment.

Hopefully everyone is satisfied with the resolution and we can all move on to future tournaments and compete the way it's supposed to be done. I'll probably be sitting out for Block n Roll because I expect to be pretty busy this upcoming week. For those of you who will compete in that tournament, good luck!
