1. Name the system
- Write the starting player condition: two letter sets, mixed ages, or already legend-ready.
- Write the action that transforms it: travel only, overlay, or structured finale.
- Write the output crossword window and the next replay date it implies.
2. Find the bottleneck
- Watch the factor that fails first: time, budget, hint count, or a thin word trail.
- Check whether the problem is tile, reset, house rules, or an unrealistic 36-minute hope on a 12-minute travel board.
- Change one stage before expanding the entire board with extra letters.
3. Keep a reserve
- Choose a minimum comfort reserve for younger players and mixed-age weeks.
- Avoid using every extra on side puzzles when the core crossword still needs attention.
- Review whether the player recovers after a temporary shortage of hints.
4. Compare after a destination refresh
When tile or rule changes affect reset or hints, update the ledger before relying on an older build order. Elena Hart will not stack a legend on a tired session in the same 18 destinations as a full challenge if the bottleneck is energy, not travel, in this mobile game.
