The aim is to light up as many bulbs of your colour as possible.
Players will take turns to place one piece on the 4-by-4 game board by clicking to select the electrical component and clicking on the square on the board to place it.
Upon placing the piece, the player can also turn that piece in any orientation (by clicking on it) within the same turn.
Players can choose to use up to two turns at any point in the game to rotate any piece that had been placed by any player.
In other words, each player has 9 turns: 7 placement turns and 2 rotation turns.
