As the title says, my short term memory has been noticeably improved due to my addiction to Kombio. I've been playing for a year now after a friend gave me their old tired deck. I've since purchased 3 more new decks as I continue to get my friends hooked. This game is the perfect combination of strategy, memory and bluffing/deception. It has seriously improved my memory for things like people's names, and other short term memory and focus.
