Nikakudori MAG is an app version of a puzzle game that lets you enjoy and train your brain. ■Rule Explanation The basic rule of Nikakudori is to connect and remove the same patterned tiles with a line. The line can be bent up to twice, and it cannot pass through places with tiles. You clear the game when all the tiles are removed. ■Zoom Function When you touch the screen for more than a second, that part will be magnified. This makes it easy to see fine parts and choose tiles even on a small screen. ■How to Change the Number of Tiles You can change the size of the board from the options. The set board size will be applied from the next game. ■Other Features When you press the back key at the bottom left of the screen, a menu will be displayed. This menu includes the UNDO function that returns the tiles you removed earlier, the HINT function that provides a hint of combinable tiles, the NewGame function that restarts the game with a new layout, and the QUIT function that exits the app. In addition, from the options, you can turn the zoom function on and off and adjust the delay time until magnification.
