A coach walks you through the end of a round at a 4-player table against bots, one move at a time. About 4 minutes.
You get a 5-letter code. Friends open this same link, enter the code, and take seats. Empty seats are filled with bots when you start. Your browser runs the game, so keep this tab open.
Your cart is your hand, in a fixed order you can never rearrange. The trolley is the face-up tile in front of each player; you may use your own section's trolley tiles in any combination, in any position. Combinations: single, set of 2–3, run of 2–4; never more than four tiles. Two players use numbers 1–6. Tiles from your cart must be side by side, and a run's cart tiles must already be in rising or falling order.
Following: same kind and size with an equal or higher number, or a Chef's Special. Chef's Special: four of a number or a run of four, all from your own cart. A set beats a run; then an equal or higher number. No combination may have more than four tiles.
Passing takes you out of the trick. When you pass you may fill any empty spot on your side with a cart tile, or swap a cart tile with a trolley tile (the taken tile goes anywhere in your cart). Used trolley tiles are not replaced.
Trick winner picks who in their section leads next. The round ends the moment every cart in one section is empty; the other section takes penalty points equal to its fullest cart. Three rounds, fewest points wins.
Every Server for Themselves: no sections; you may use, fill and swap only your own and your two neighbors' spots; the trick winner leads; the round ends when any cart is empty and everyone else scores their own cart.
