Can you arrange four colourful stones in a row? Sounds easy, but here your game opponents might have something to say about that. This way it very quickly becomes a nail-biting challenge. Whoever is the first to place four stones of the same colour side by side in the 7 x 6 grid, wins the challenge.
Whilst alternating turns you drop red or yellow pieces vertically into the 7 columns of the game grid. The duel begins in no time at all! You take it in turns to drop the stones, but there can only be one winner.
In this game, it’s always 2 players with the same initial situation that play against each other. This does not necessarily happen immediately, but can also happen with a time delay (also see How do single-player games work?). The battle takes place with an arsenal of 21 red and yellow playing stones. The playing field (grid) consists of 42 holes, which are to be gradually filled with stones.
Chance determines what colour you play with in the round, and who can cast the first stone into the grid.
Once it’s you're turn, you choose in which of the 7 columns you would like to drop your playing stone with a mouse click. The stones can only be dropped into the grid vertically. One by one you try now to arrange 4 stones of the same colour next to each other. This can happen horizontally, vertically or diagonally.
You may only drop one stone per turn. Think long and hard about which column you would like to drop your stone in, because often it helps to have a good strategy at hand from the outset. Be careful where your opponent might place their four rows and try to thwart their plans.
End of the game
The first one to get four stones of the same colour in a row, wins the game.
