This edition was produced for the Spring 2015 Tokyo Game Market (TGM). It differs largely from the second editon, because it was produced to satisfy the Spring 2015 TGM design challenge '2種カードゲー企画' which was to bring games using only two types of cards. For the following TGM, the designers revised the game since the restrictions of the challenge did not apply.
This first editon is cards only, has a smaller game field, and different behaviour of the Hares. The first edition has a smaller play field 3 x 4 (instead of 5 x 6), only uses cards for play, and the Hares change power when they flip, instead of changing movement. The theme and goals of both Versions are the same, but in the designers' experience, the first editon leads to a fourway stand-off.
