10.hs

Haskell implementation of modified 2048

How to play

To start the game, run

make run

(See the requirements if this doesn't work.)

10 is a slightly modified version of 2048, the very smart puzzle game by Gabriele Cirulli.

The only differences are:

• In 10, numbers grow linearly (1, 2, 3, 4, 5, etc) where in 2048, they grow exponentially (1, 2, 4, 8, 16, etc).
• In 10, you win and the game ends when you get to 10, where in 2048, you win when you get to 2048, but you can keep playing.

Why the changes? Because I'm completely new to Haskell, and I didn't want to deal with string formatting, that's why 😇 This makes 10 slightly easier than 2048, because 2^10 is only 1024.

When you start a game, you will see a 5x5 board (the size is a parameter in the source code, so you can easily tweak it). The board is mostly empty -- empty cells are indicated by periods (.) -- but there will be one non-empty cell. For example:

. . . . .
. 1 . . .
. . . . .
. . . . .
. . . . .

You will also see a prompt to "enter wasd". Choose a direction - up, down, left or right, by entering the corresponding wasd key, and hit return. Two things will now happen. One: the pieces on the board slide in the direction of your choice. And two: the computer places a new piece on the board, indicated by an asterisk. This new piece will usually be a 1, but sometimes you'll get a sneaky 2. For example, after entering w for up, you might get:

. 1 . . 1*
. . . . .
. . . . .
. . . . .

A third thing that will start happening pretty soon, is that when two pieces with the same value slide into each other, they merge. For example, after entering d for right:

. . . . 2
. . . . .
. . . . .
. . 1*. .
. . . . .

And so on.

The goal of the game is to keep merging pieces together until you merge two 9s, giving you a 10.

But be careful! If the board fills up and you have no available moves, you lose.

You will also note that the computer won't place a piece unless you actually move the pieces. For example, if you have

1*. . . .
2 . . . .
. . . . .
. . . . .
. . . . .

and you enter a for left, or w for up, the board doesn't change, and you don't get a new piece. No soup for you!

Have fun.
