This is a christmas themed version of the cube crash game (not on newgrounds). The game has score boards, but they only store your scores and you can't see others scores.
There is nothing fancy about this game and it is not original, just a clone of a clone... But people still seem to enjoy it! So if you like this type of game then have fun!
Sensless clicking is the worst way to play this game due to the way scoring works. 6 blocks clicked as 2 groups of 3 is worth less than one click on a group of 6... The goal is to collect as many together as possible for one huge group than doing them all individually. Making the scoring work this way makes the game more about strategy in that you have to figure out the best blocks to remove at the beginning to make the hugest group.
