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.

So ... so so

This seems to be a remake/copy/steal of an earlier game posted years ago on Newgrounds but that one had 1 and 2 player options and used blue and red. Im looking for it but can't find it yet.

This game is somewhat of a troll in that what appears at first to be a strategy game instead is more a casino game. Go ahead and put this in casinos and require people to get > 850, 900, 950, and 1000 points to cash out and watch that casino rake in the money on this one.

Anything lower than 10 is just awful, but particularly when it's giving you such fine numbers as 3 and 1 while meanwhile the computer gets 15 and 19. It's mostly down to luck of the numbers it gives you.

There is no effective strategy here at all (for obtaining any of the high score medals) other than don't just plop them down willy-nilly and do try to protect what's already there and take what you can, but it's still not even close to enough because in the end the luck element is the only thing which might ever grant you those medals.

Is it trivially easy to beat the computer player in points at the end? Yes. But that doesn't get you a medal or anything. Game is like 0.0001% skill, 99.9999% luck if you want all medals. Or even if you just want that 850 points medal sheesh!

It's simple and I'm a big fan of simple games. However, as many people have stated already the random element of the tiles make hard to create a effective strategy. This also makes getting the point medals exceedingly difficult. Personally I like the challenge.
