> which really only took the "two tiles with the same numbers merge when they collide" element from Threes
Which is the only element Threes has!
Which is the only element Threes has!
The bottom line is that Threes is a much better game than any of the clones I've played. There's a subtlety and polish to the gameplay that is missing from the others. It's obvious they spent a lot of time perfecting everything from the tile distribution to where they spawn and how they merge.
It's just not smooth enough from start -> play -> restart -> restart to be a good casual gaming experience. It's start -> thud -> thud -> play -> thud -> thud -> restart -> right, back to 2048 then.
