Ninja Dojo Fight! is a board game released in 2015 for 2–4 players, 8–15 minutes per game, and ages 7 and up. It was designed by Allen Chang and Alannah Kearney and its main mechanics are Set Collection, Simultaneous Action Selection, and Rock-Paper-Scissors.
The aim in Ninja Dojo Fight! is to prove you're the best Ninja by participating in unsanctioned battles. To help you win, you must break into the dojo and look for the best weapon you can find at the break of dawn. The game is made up of five rounds with each round consisting of three turns followed by a battle phase. Each turn has three phases: Select: Each player secretly chooses an action. Reveal: All players simultaneously reveal their chosen action. Resolve: Actions are resolved in ascending order. After three turns, a battle occurs and a new round begins. The player to win the most battles after five rounds is declared the winner. In the event of a tie, the players tied play one additional round, called the showdown; whoever wins the showdown wins the game. --- Ninja Dojo Fight! is a micro game inspired by Entropy. You play as a ninja from one of four rival disciplines. As a ninja in training on your final test, your goal is to win the most battles using the weapons at your disposal. The game play has similarly to the main counterpart Entropy, through the use of simultaneous action selection, but it's not quite the same game. With only 42 cards, it is more thematically and technically accessible than Entropy. The visual design is minimalistic and the cards do not have any text.
Ninja Dojo Fight! supports 2–4 players according to the catalogue. This range comes from the publisher’s listed player count, so the game can be set up for any group size within it.
