The title: Reakcja ?a?cuchowa travel: Do??cz ogniwo would be translated to Chain reaction travel: Add a link. In this game players add tiles to the grid of tiles (which starts from the size of 5x8).
On their turn a player has to draw a tile and add it on top of one of the five grid's columns. After the placement they check if there is a tile with matching symbol on the left, right and bottom (in this order) side of the added tile. If there is a match the player takes the other tile (not the tile just placed) and add it to their pool. After taking a tile from the grid it may happen that there is an empty space, so every tile the has empty space beneath it drops down, which may cause more matches (the matches are checked only with the just added tile) and so on.

The game ends when one column is empty or the stack is depleted.

The players earn point from individual tiles, objective tiles (contracts - gathered during the game) and secret color tiles (assigned at the beginning of the game).
