Though I'd not say it perfect, it actually isn't that hard. We don't "prevent" it from being formed, but find them out and draw an item or two away. If they got too much, try to match a six.
And collected bonuses appear on the left, you gotta click them to use them.
I couldn't figure out the game from 6th try.
OVERALL: This sucks : | .
Specials never seemed to go away and also, for whatever reason, spotting the sets of three was nearly impossible. I'm not saying the challenge was a bad thing, don't get me wrong, but I personally couldn't stop a single set of three from being formed except the very first one I saw in every game I played. And if a game is too hard, it kind of makes it not so fun. And this definitely qualifies, because the only way sets of three got destroyed was by chance when the board changed. Additionally, one time I got really lucky, and got pretty far, and the pieces were just disappearing immediately over and over again, instantaneously, making any moves I might have made, completely pointless. Also not so fun. Not a bad game, but not so good either.
