Best Link is a fun nikakudori or mahjong connect game. The objective of the game is to match up all of the pairs. While the tiles are placed on the board face up and the pairs are easy to spot, the tricky part is connecting them. That’s because the line that is drawn between the tiles you’ve selected may only turn two 90-degree corners at most. This is why these matching puzzles are sometimes called by their Japanese name, ‘nikakudori’, which means ‘two-corner street’.
