Game Rules & Data Structures + +We implement standard Spider Solitaire. +- **Decks**: 2 decks (104 cards total). +- **Suits**: Support 1-suit (Spades), 2-suit (Spades, Hearts), or 4-suit (standard) configurations. 1-suit is the default and recommended for terminal play. +- **Tableau**: 10 columns. + - Setup: First 4 columns get 6 cards (5 facedown, 1 faceup). Next 6 columns get 5 cards (4 facedown, 1 faceup). + - The remaining 50 cards form the Stock. +- **Deals**: Dealing from Stock puts 1 card faceup on each of the 10 columns. Standard rule: Stock cannot be dealt if there are any empty columns. +- **Move Rules**: + - A sequence of faceup cards can be moved if they are of the *same suit* and in *decreasing numerical order* (e.g., 9♠, 8♠, 7♠). + - A sequence/card can be placed onto any faceup card of any suit that is exactly one rank higher (e.g., placing a 7♠ on an 8♥), or onto an empty column. +- **Clearing Runs**: + - If a full same-suit sequence from King down to Ace (K, Q, J, 10, 9, 8, 7, 6, 5, 4, 3, 2, A) is formed in a column, it is cleared from the board and placed into the completed foundations. +- **Win Condition**: All 8 runs are cleared (104 cards). + +### Data Models (`card-game-app/game.py`) +- `Card`: + - `suit`: Str (e.g. `'♠'`, `'♥'`, `'♦'`, `'♣'`) + - `rank`: Int (1 for Ace, 11 for Jack, 12 for Queen, 13 for King) + - `face_up`: Bool +- `SpiderGame`: + - `tableau`: List of 10 lists of `Card` + - `stock`: List of `Card` + - `completed_runs`: Int (0 to 8) + - `undo_stack`: List of game state snapshots (memento pattern using deepcopy) + - `suits_count`: Int (1, 2, or 4) + +--- + +## 2. Terminal Rendering Approach (`curses`) + +Using Python's standard-library `curses` module. To make it highly visually clear: +- **Card Styling**: + - Hearts/Diamonds in Red. + - Spades/Clubs in default/white. + - Facedown cards represented with a distinct background/pattern like `[░░░]` or `[###]`. + - Selected cards highlighted (reverse video/bold/yellow). +- **Layout & Positioning**: + - We divide the terminal into columns. An 80-character terminal easily accommodates 10 columns of width 6 with 1-char gaps: + `Column X = col_idx * 7 + 2` + - Stacking cards: To fit long columns vertically, we stack cards. Only the top-most part of a card in a stack is rendered (e.g., `| 9♠|`), and the bottom card is drawn fully (e.g. `[ 9♠]`). This takes only 1 line per card plus 1 line for the bottom card! +- **Header/Footer**: + - Header: Shows stock count, completed runs count, and current game mode (e.g., "1-Suit"). + - Footer: Interactive guide ("Arrows: Move, Enter: Select/Drop, U: Undo, D: Deal, R: Restart, Q: Quit"). + - Status/Error line for messages like "Invalid move!" or "Cannot deal with empty columns!". + +--- + +## 3. Input Handling & Move/Action Validation + +We use a simple state machine for the UI: +1. **IDLE State**: + - Left/Right Arrows: Move column cursor (0-9). + - Up/Down Arrows: Navigate *up* and *down* within the face-up cards of the current column to select where to split/move the sequence. + - Enter/Space: Validate if the highlighted card and all cards below it form a valid same-suit decreasing sequence. If yes, transition to **SELECTED State** and save the selection. + - `u` / `U`: Undo. + - `d` / `D`: Deal stock. + - `r` / `R`: Restart game. + - `q` / `Q`: Quit. +2. **SELECTED State**: + - Left/Right Arrows: Move destination column cursor (0-9). + - Enter/Space: Attempt to move selected cards to the target column. + - Validate destination card rank (must be selected card rank + 1, or column must be empty). + - If valid: perform move, flip new top card if needed, check for completed run, push to undo stack, return to **IDLE State**. + - If invalid: show error message, stay in SELECTED state (or escape). + - Escape: Cancel selection, return to **IDLE State**. + +--- + +## 4. Win/Loss Detection + +- **Win**: Triggered when `completed_runs == 8`. A victory screen is shown. +- **Loss/Stuck**: There is no hard loss state in solitaire, but we can display a status message if no valid moves are possible on the board and the stock is empty. + +--- + +## 5.
