Adds up both sides of a proposed trade in one game and answers win, fair or lose, with the gap in per cent. Both sides are written as the player would say them: "2 party balloons, sakura" or "neon shadow dragon". A trade that mixes two games is refused rather than calculated: the three games use different scales that cannot be added together.
