Take your time kyttias! An easy way to hook games up would be awesome ^^

Every "game" would need to either

A) follow the same specific "Send Score" design
B) every game would need to be edited to follow the same "Send Score" design.


The PHP part for score could be the same base that could work with every HTML5 game, but EVERY game would need to follow the same pattern of sending the score to the PHP file.

Either way, A or B still needs to be done.

More or less, yeah. Some games are simple enough to follow standard, others may need something more complex... but once you've done it once, it shouldn't be hard to edit (if you know what you're doing). My current system just kind of sends a 1:1 score to currency, so if you earn 1000 points you get 1000 currency... other games may different and need to convert the score to a proper amount of currency. And it all could really use some better security.

Anti-cheating mechanisms are important and the more unique it is for each game, the better. Checking if a score is even possible is important.

Anti-cheating mechanisms are very important. That will be the hardest part itself. Every game would require its own anti-cheat file/code. Anti-cheating wouldn't really be needed at first. The more popular these types of systems are the more it is trying to be exploited. I believe in time/score kind of anti-cheating system most of the time.

Ex: Tetris
If you submitted a score with 73 lines cleared in 40 seconds. You a Tetris code. j/k. CHEATER!
