Tachra is an intellectual laser game that accommodates different ages. The game is between two teams who compete to destroy a bad symbol. In Tachra, laser lights are guided by mirrors and they operate in a netted rectangular plate. Apart from the plate, there are 25 pieces. Each team has 1 laser, 2 two-sided mirrors, and 7 one-sided mirrors. There is also 1 bad symbol, and 4 pieces which protect the bad symbol. The pieces are allowed to be moved in 8 directions and rotated 90 degrees. The bad symbol is destroyed after it has been hit 7 times. The winner is the team who has been able to hit the bad symbol more, or for the final time.
