Electronic gaming system with main monitor displaying public part of game and several terminals, each operating in gaming or controller mode. In gaming mode the terminal displays private parts of the game to user, and user's actions control object on terminal. In controller mode, main display is replicated on terminal display, and user's actions on private terminal are replicated on main display. Example, moving tile on the terminal will send “move tile” to move the same tile on the main monitor and all other terminals. The terminals support zoom and board shift to access any part of the bigger board. It also supports store and forward functions, enabling user to prepare next move privately before sending to main monitor. When the terminal is in controller mode, its processor may constantly synchronize the view of the terminal with the main monitor.
