Purpose

Document the shipped Spell Puzzle built-in game behavior.

Requirements

Requirement: Registry Metadata

Spell Puzzle SHALL be registered as a built-in game with canonical description "Connect letters to fill a crossword with bonus anagrams.", aliases spell, spellpuzzle, variants Spell Puzzle (default 1500 Elo), and daily legacy modes beginner.

Scenario: Resolve Spell Puzzle

• WHEN the registry resolves the canonical name or any alias
• THEN it returns the Spell Puzzle entry with help text, import behavior, variant metadata, and legacy mode compatibility

Requirement: Variant Elo Creation

Spell Puzzle MUST support the current variant plus target Elo creation path, using the variant default Elo when no explicit target is supplied.

Scenario: Spawn Spell Puzzle by Elo

• WHEN the user selects the Spell Puzzle variant and a target Elo from 0 through 3000
• THEN PuzzleTea spawns a deterministic Spell Puzzle puzzle and records target, actual, and confidence metadata when generation reports it

Requirement: Legacy Mode Compatibility

Spell Puzzle SHALL preserve legacy named modes as compatibility presets that map to the Spell Puzzle variant and preset Elo values: Beginner (0 Elo), Easy (600 Elo), Medium (1500 Elo), Hard (2400 Elo).

Scenario: Use legacy mode title

• WHEN the user supplies a legacy Spell Puzzle mode title through CLI or deterministic daily metadata
• THEN PuzzleTea resolves it to the Spell Puzzle variant and the registered preset Elo

Requirement: Puzzle Rules

The Spell Puzzle runtime MUST let players connect wheel letters to fill crossword board words and track valid bonus anagrams without requiring bonus words for puzzle completion.

Scenario: Check solved state

• WHEN the player fills the board or word state
• THEN Spell Puzzle reports solved only when all rule constraints are satisfied

Requirement: Save Load And Interaction

Spell Puzzle SHALL serialize enough state for resume/import, reset to its initial puzzle, expose debug and full-help data, and support its shipped interaction model. Keyboard word entry is required, and mouse drag support MUST be available.

Scenario: Resume saved Spell Puzzle

• WHEN a saved Spell Puzzle payload is imported
• THEN the restored game preserves givens, player entries, cursor/selection state where applicable, and solved-state behavior

Requirement: Print Export Support

The Spell Puzzle print adapter SHALL render puzzle and solution data for JSONL-to-PDF workflows.

Scenario: Export Spell Puzzle

• WHEN Spell Puzzle is included in a JSONL or PDF export flow
• THEN PuzzleTea follows the registered print support behavior for that game
