You can also use Cash Blox to play an automatic version of Cash Blox, which comes from Playtech, which gives players the frustration of watching the falling blocks without having to actually do anything.
Play or auto play to start the block down. If you want to see what happens in slow motion, use the slow mode button. When the block descends, any complete lines or lines will disappear and the new lines will fall from the top to replace them.
