I have to disagree with some of the earlier detractors:
Knowing that you have a low value tile means you need to think how to use it effectively.
Depending on the point in the game, and how the tiles are going, there are 3 distinct ways I might use those low tiles.
If the game were all about who gets the higher tiles, then the win / loss should be about 50/50, but good strategy makes it possible to beat the computer, even to beat it soundly.
The 850 medal was achieved on my 2nd play through, once I better understood how the game works, so it isn't down to 1% skill.
To improve the game further, I'd suggest some different boards maybe.
I'm not sure if knowing your next tile, or the enemies next tile, would make the game better or worse.
Likewise, getting to choose the order you play tiles would be interesting idea.
eg - your next 3 tiles are 3,8 and 11, and you choose which order to play them.
It would also be interesting to see the average tile played for each side, or otherwise have some post game statistics to help gain understanding.
Did I play badly? Or was the enemy just getting better tiles this game vs last? etc.
