Rule presets

Japanese Transitional

This rule preset represents a kind of a mid-point between the classical and modern versions of Japanese Mah Jong. In addition to rule of Riichi (voluntary declaration of Ready), several new patterns are introduced, often with different scoring for composing them of concealed or partially melded sets (note the difference to the modern Japanese Mah Jong, where a higher scoring is often given for having a pattern in a concealed hand [winning tile can be claimed], in which case one of the composing sets, if it completes the hand, can be melded).

Many traditional patterns have been given a slightly higher score and initial points have been raised to 8,000 points, limit being 1,500 points. Transitional rules also use simplified versions of rules typically used in modern Japanese, e.g., payments for ready players after a draw, and bonus for dealer's extra hands.
