The German company Public Solution has produced five RFID based games, published under the name Yvio, including Elefant, Tiger, and Co., Octago (by Reiner Knizia), Thinx, FreiBeuter Der Karibik, and Tarascon, with another game on the way. The games’ boards not only detect and identify pieces, but can generate random values and save game states for later use.
