A pocket toolkit for friendly mahjong nights — five focused helpers that replace dice cups, paper notes, and side timers. Pick the dealer or determine the wall break with one or two animated dice. Choose between 6-sided or custom 4-sided variants, watch the rolling animation, and read the live histogram of past rolls before exporting the result. enerate a random 13-tile starting hand using a full 136-tile wall. Toggle inclusion of flowers, restrict to a single suit for drills, or tighten honour-tile probability to study tenpai shapes. The result panel can be exported as a PDF cheat sheet. Mimic the physical shuffle ritual. Configure rounds, animation speed and stack height. The visualiser shows tiles cascading and re-stacking, and a small bar chart tracks how evenly tiles are distributed across the four walls. Assign East · South · West · North without arguments. Enter player names, optionally seed by a previous winner, and run the lottery. A compass diagram displays the final positions and a PDF roster can be saved for tournament records."A countdown for the player on turn. Adjust seconds with a slider or segmented presets, enable warning haptics at the last five seconds, and turn on auto-restart between turns. A circular progress ring keeps the table glance-friendly.
