About RoRop, from BoardGameGeek:
To score in RoRop, you must collect wooden blocks.
The game consists of a wooden game board and 36 blocks, six each in six colors. To set up, set the game board up diagonally, then take one block of each color and place one at the bottom of each of the six columns in the game board. Finally, add the other blocks in the columns, taking care not to place the same color orthogonally adjacent.
On a turn, a player chooses a color present on the bottom row of the game board, then takes one or more blocks of this color from the bottom of the board. Keep taking turns until all of the blocks have been claimed, then tally your score.
In the basic game, your score is the number of blocks you claimed. In the intermediate game add to this number the product of the number of different colors you claimed and the number of blocks in your most prevalent color. In the expert game, score the product of the number of different colors you claimed and the number of blocks in your first claimed color, then add the number of blocks you collected.
You can also use the RoRop components to play a four-in-a-row game. Starting with the empty game board, on a turn either (a) add a block to the top of any column or (b) remove a block from the bottom of any column, then place it on the top of any column. If a player takes the (b) action, the next player must take an (a) action, if possible. If you create a line of four blocks of the same color, whether orthogonally or diagonally, you win.
