[OUTDATED] I'll explain the rules for playing this game in real life, then I'll explain how to use the online version, and what's different. RULES: Make the tiles out of paper or something; shuffle each color and give both players stacks (one of white tiles, and one of black tiles). Starting with the player using the white tiles, players will take turns placing tiles with the goal of being the first to get four in a row. On your turn, draw a tile from the top of your stack to place. There is no board; instead tiles are placed directly on the playing surface according to an imaginary grid. Theoretically, there is no limit to how large the playing surface can be, but if you reach the edge of the physical surface (such as a table), just don't place tiles any farther away. Apart from the very first one, which is placed in the rough center of the playing surface, tiles can only be placed in a spot if the other tiles around that spot allow it. You can place them according to these rules: They can be placed directly next to Plus ( + ) tiles, diagonals not included. They can be placed directly next to Ex ( × ) tiles, but only diagonally. They can be placed directly next to Star ( ⁕ ) tiles in any direction. Dot ( • ) tiles don't add spots for tiles to be placed. However, they don't *prevent* placement, so you can still place tiles next to them if other surrounding tiles allow for it. You can decide how many of each tile to put in each player's stack. If you have no tiles to place on your turn, you must move one of your placed tiles to a different spot. When moving a tile, you must follow the same rules as when placing one, with the additional rule that you *cannot* leave surrounding tiles completely disconnected from the rest. Keep in mind that different tiles connect differently. Not every game will be long enough to start moving tiles. WINNING: As previously stated, you win if you manage to place four of your tiles in a row in any direction... that's about everything. ONLINE INSTRUCTIONS: I'll go ahead and say that I'm not a great programmer, and most of these differences are because I couldn't find a way to implement something into this project. Press the green flag to start/reset. The gray tile in the center of the bar is the tile selector. Instead of shuffling tiles, you will use it to randomly select a tile to play. Click on it to decide what tile you must play. Once you know what tile to play, drag the matching tile of your color to the rough center of the blank playing area. The tiles in the bar are unlimited in supply, and clicking on one (even one in the playing area) will make a copy of it. If a tile is in the playing area, dragging on it (rather than just clicking on it) will simply move it, rather than copying it. Luckily, this doesn't affect gameplay too much, and any unwanted tiles can be removed by dragging them to the edge of the screen. Since you can't really "run out of tiles" here, the moving phase is triggered after 24 tiles have been placed as indicated by the counter at the bottom of the screen. Pressing on the tile selector makes the counter tick up.
I had little help in the creation of this game. However, the idea of placing tiles down without a board is from a game called Schachen (ChessMe), a Chess variant by Matthias Schmitt and Heinrich Glumpler. Thanks to @Scratch_Cybernetics for the grid-snapping tutorial (though I had to tweak the numbers). If you have any confusion about the rules of the game, or how to use this online version, please tell me in the comments. I'd like to hear feedback too, so let me know what you like/dislike about this game; I might make changes! Also, if you know a way to fix the bug of being able to copy tiles that are already placed in the playing area, I will gladly put you up there in the credits. ^ Actually, Development of this Scratch project is probably over (I think I have a fix for some bugs, but I don't feel like implementing it). By the way, I don't really like the name, so I'll probably change it someday. A physical version of this game (with improvements) is currently being produced under a different name. :)
