This is like the classic number game, 2048, but instead of a square, it's a hexagon! When you make a move, (for example, right), all the tiles will move as far to the right as they can. If two tiles with the same number hit each other, they combine into the next one up! If you haven't played classic 2048 before, go to play2048.co to try it first.
To control the game with the keyboard, use the keys ZAWEDX, because they kind of make a hexagon around the "s" key. If you use a different keyboard layout (like me), you can still use the keys in these places and it will work fine. On a touchscreen, you can swipe in the direction to go. Just remember that the pieces travel toward corners, not edges like in regular 2048.
Yes, they are. The movement of the pieces can seem a little counterintuitive, such as pices not going all the way down when down-left is pressed, but I can promise you that the movement is working just as it is intended to. The pieces will move in straight lines for as far as they can. This means that down-left makes the pieces move, well, down-left as far as they can go. Not down. Not left. Down-left.
This seems to be a little easier than regular 2048, so you won't get notified if you win. I find 4096 to be a reasonable goal. As for strategy? That's for you to figure out :)
