Boss Ranger (bossranger.com) helps poker players improve their ranging skills in the real game environment. Basically, it’s just like playing real poker but instead of deciding which action to take (bet, raise, call, fold), the aim of the game is to work out which hands you think your opponent might have in their range. For this goal, the simulator for guessing opponent’s cards was developed. It’s the first poker tool of its kind, it allows poker players to test their hand reading abilities versus other poker players. Boss Ranger allows players to practice guessing player’s hand ranges in a real game scenario. After guessing they will get an immediate result. Boss Ranger profits by charging players a monthly subscription fee, which will give subscribers access to the entire library of games.
