Yet another resolution to Impasse is the so-called Try Rule (トライルール "torairūru"). In this case, after both kings have entered their corresponding promotion zones, then the player who first moves the king to the opponent's king's start square (51 for Black, 59 for White) first will be the winner. As an example, the popular 将棋ウォーズ (Shogi Wars) app by HEROZ Inc. used the Try Rule up until 2014. (Now the app uses a variant of the 27-Point Declaration Rule – although it differs from the variant used on the 81Dojo site.) The idea of "Try Rule" was taken from rugby football (see Try (rugby)).
