Introduction
Why Training?
Tile efficiency is fundamental to mahjong skills. Systematic training helps improve reading speed, optimize discard choices, and enhance actual gameplay performance.
General Settings
Tile Count
Choose between 13-tile or 14-tile modes depending on the training type.
Difficulty Level
From easy to hard, different difficulties affect hand complexity.
Timer
Set time limits for answering to simulate real-game pressure.
Keyboard Shortcuts
Tenpai Training
Training Steps
- System randomly generates a 13-tile ready hand
- Observe the hand and identify waiting tiles
- Click or use keyboard shortcuts to select waiting tiles
- Submit answer to view results
Example Hands
Example 1: Two-sided Wait
This hand is waiting for 4p or 7p. This is a typical two-sided wait.
Breakdown: m123, m456, m789 (3 sequences), s88 (pair), p56 (taatsu)
Example 2: Single Wait
This hand is waiting for 9p. This is a single wait.
Breakdown: m111, m222, m333 (3 triplets), p123 (sequence), p9 (single tile)
Example 3: Three-sided Wait
This hand is waiting for 1m, 4m, or 7m. This is a three-sided wait.
Breakdown: m234 (sequence) + m56 (taatsu, waits 4, 7), or m23 (taatsu, waits 1, 4) + m456 (sequence); p123, s123 (2 sequences), p99 (pair)
💡 Training Tips
- Start with easy difficulty to familiarize yourself with common ready hand patterns
- Learn to distinguish between two-sided, single, and multi-sided waits
- Gradually increase difficulty to challenge complex hands
- Practice improves recognition speed for better in-game decisions
Heqie Training
Training Steps
- System generates 14 tiles
- Analyze the hand to find the best discard
- Select the tile to discard
- View correct answer and explanation
Example Hands
Example 1: Discard Isolated Tile
Discard 1s because it's isolated and doesn't help the hand structure.
After discarding 1s, the hand maintains one-shanten status with maximum efficiency.
Example 2: Discard Edge Tile
Discard 1s because it's an isolated edge tile unrelated to the hand structure. After discarding, wait for 1m, 4m, or 7m (11 tiles).
Breakdown: m234, p456, s789 (3 sequences), m99 (pair), m56 (two-sided taatsu), s1 (isolated edge tile). Discarding 1s keeps the two-sided taatsu m56 for maximum wait width.
Example 3: Discard Extra Pair
Discard 5m, breaking up the m55 pair while keeping p99 as the pair head. This creates a wait for 3m and 6m (7 tiles, two-sided wait).
Breakdown: m1234 (4 consecutive tiles), p456, s789 (2 sequences), m55, p99 (2 pairs). If discarding 1m or 4m instead, you can only wait on shanpon for 5m and 9p (4 tiles), which is less efficient.
💡 Training Tips
- Focus on which tile is least beneficial for future draws, prioritize discarding isolated and edge tiles
- Analyze shanten changes after discard, choose the option that minimizes shanten
- Keep taatsu that can form multi-sided waits
- In actual gameplay, also consider safe tiles and reading opponents
One Shanten Training
Training Steps
- Observe 13 tiles
- Identify effective tiles (tiles that can make the hand ready)
- Select all effective tiles
- Submit answer
Example Hands
Example 1: Missing One Taatsu
This hand is one shanten. Effective tiles include: 1m, 2m, 3m, 4m, 5m, 6m, 7m, 8m, 9m.
Hand has: m223, m345, m567, m999 (3 sequences + 1 triplet), missing one taatsu or pair.
Example 2: Missing Pair
This hand is one shanten. Effective tiles are all tiles that can form a pair.
Hand has: m123, m456, m789, p12, s12 (3 sequences + 2 taatsu), missing one pair.
Example 3: Complex One Shanten
This hand is one shanten. Effective tiles include 1p, 3p, 2s, etc. (completing sequences or taatsu).
Hand has: m123, m456, m789 (3 sequences), p12 and s13 (two taatsu), missing one meld.
💡 Training Tips
- First analyze what taatsu or pair is missing, then deduce effective tiles
- Don't miss any possible effective tiles
- Practice improves recognition speed and accuracy
- Understanding effective tiles helps make better decisions in actual gameplay
Shanten Calculation
Training Steps
- Observe the hand
- Calculate how many steps away from tenpai
- Enter the shanten number
- View answer
Example Hands
Example 1: 2 Shanten
This hand has 2 shanten.
Hand structure: Has some taatsu, but needs 2 effective draws to reach tenpai.
Example 2: 1 Shanten
This hand has 1 shanten.
Hand structure: Has m123, m456, m789 (3 sequences), p12 and s12 (two taatsu), one meld away from tenpai.
Example 3: 0 Shanten (Tenpai)
This hand has 0 shanten, already in tenpai.
Hand structure: Has m123, m456, m789 (3 sequences), s88 (pair), p56 (taatsu).
Example 4: 3 Shanten
This hand has 3 shanten.
Hand structure: Tiles are scattered, needs many draws to reach tenpai.
💡 Training Tips
- Remember standard winning form needs 4 sets + 1 pair, add one shanten for each missing taatsu
- Quickly identify existing taatsu, triplets, and pairs in the hand
- Calculate how many effective draws are needed to reach tenpai
- Practice improves calculation speed and accuracy
One Shanten Discard Training
Training Steps
- Confirm hand is in one shanten
- Analyze effective tile count after discarding each tile
- Choose the discard option with most effective tiles
- Submit answer
Example Hands
Example 1: Retain Most Effective Tiles
Discard 1p to retain the most effective tiles.
After discarding 1p, hand retains more taatsu with maximum effective tiles.
Example 2: Avoid Breaking Multi-sided Wait
Choose discard option that can form multi-sided waits.
Keep taatsu that can form multi-sided waits, avoid discarding key tiles.
Example 3: Balance Effective Tiles and Wait Width
Balance effective tile count and wait width after tenpai.
Consider not only effective tile count but also waiting tile count after tenpai.
💡 Training Tips
- Focus on taatsu efficiency and hand flexibility, avoid breaking multi-sided wait possibilities
- Calculate effective tile count for each discard option, choose the one with most
- Consider wait width after tenpai, prioritize multi-sided waits
- Keep taatsu that can form good shapes
