Synapse Chain

Highly difficult puzzle game

Synapse Chain is a challenging puzzle game for experienced puzzlers. It is not recommended for the general public.
The objective is to place all 256 pieces, each with lines drawn in eight directions, on a 16x16 grid. Pieces must be placed vertically, horizontally, and diagonally so that they connect with the lines of adjacent pieces. Lines cannot extend around the perimeter of the grid.
First, placing 256 pieces manually can be extremely difficult. Therefore, try using the random placement function. Press and hold this button to randomly place available pieces.
You can move panels by dragging them from the stock area at the bottom of the screen or from grids already placed. If you attempt to move a panel to an unavailable location, that grid will turn red. Additionally, tapping an empty grid will highlight pieces that can be placed there. Utilize these features to complete the puzzle.
There is more than one solution, but placing all the pieces is extremely difficult. Completed placements are saved and can be reviewed at any time.
Due to the high level of detail on the screen, we recommend playing with a tablet or mouse.
We reiterate that this game is not recommended for the general public. We look forward to the challenge of those confident in their skills.
