Overview

Tsukuru 10 Ten (Make 10 Marten) is a 👤2players to 👤4players player set collection game similar to Mahjong. Each round, players race to complete and score a value 10 hand of 8 tiles.

Tiles

The game is played with a set of red, blue, and purple tiles with values ranging from 0 to 8:

• 🎴 4 x blue 1 2 3 4 5 6 7
• 🎴 4 x red 1 2 3 4 5 6 7
• 🎴 1 x red 0
• 🎴 1 x purple 5 6 7 8

Purple is a wild color, so a purple tile can be used as if was a red or a blue tile.

Gameplay

A game round starts with each player receiving 7 starting tiles face down. The round proceeds with each player taking one of available actions, starting with the dealer and going clockwise.

The dealer is decided randomly in the first round, and after a round's end the player on the dealer's left becomes a new dealer.

During a turn, each player choses one of the following actions:

• 🦦 Draw : take a new tile from the deck and add it to your hand. If the new tile completes the hand, you can declare victory by revealing it (see Finishing).
• 🦦 Get : take the last tile from an opponent's discard and add two more tiles from your hand to form an open set (see Sets).
• 🦦 Finish from discard : take the last tile from an opponent's discard and use it to complete your hand (see Finishing).

If the action didn't end the round, you must discard one of the tiles from your hand.

Sets

There are 3 kinds of sets that can be formed with the tiles to reduce their total value. Each consists of exactly 3 tiles and is counted as follows

• 🎴 3 sequential blue tiles have the value of the lowest blue tile.
• 🎴 3 sequential red tiles have the value of the highest red tile.
• 🎴 3 equal tiles of the same color have the value of 0.

If a set is formed by taking Get action, it's revealed to other players and becomes an open set. Otherwise, it's not necessary to commit to any set configuration, and which tiles become parts of sets is only decided when revealing a hand.

Here are some valid set examples:

• ✔ 4 5 6 = 4
• ✔ 1 2 3 = 3
• ✔ 5 5 5 = 0
• ✔ 2 3 4 = 2

When adding a purple tile to a set, it's automatically converted to a red/blue tile depending on the set color. A set made completely from purple tiles can be considered as either color. In a rare case of forming an open set with 3 purple tiles, their color needs to be chosen immediately when revealing the set.

Finishing

A player can finish the round by revealing a hand of 8 tiles if the sum of the tiles is exactly 10 (after evaluating the sets). This can be done either after drawing a tile from the deck, or by taking Finish from discard action (see Gameplay).

In both cases, it's necessary to first select "Finish'" and then select the tiles necessary for the final hand's sets. The remaining tiles count as their own value.

The player who reveals a valid winning hand scores 1 point.

Advanced Scoring (Hand Bonuses)

With advanced scoring rules, each winning hand may score bonus points upon revealing. The base score is changed to 3 points for the dealer, who'd drawn the first tile in the round, and 2 points for other players. After that all matching bonuses add corresponding points as long as they're not mutually exclusive.

Each free Marten tile must be assigned either Red or Blue color before evaluating the hand.
