Stacking Rules

TileTangle supports Upwords-like stacking:

• Enable stacking and set constraints on the rules:
  • stacking_enabled: allow placing on occupied cells.
  • stacking_max_height: maximum stack height per cell.
  • forbid_same_symbol_overlay: disallow placing the same symbol on top.
  • stacking_scoring: TopOnly (default) or SumStack.

Web (WASM)

const g = mod.new_game(JSON.stringify(cfg), 2);
mod.set_stacking(g, /*enabled*/ true, /*max*/ 7, /*forbidSame*/ true, /*sumStack*/ true);

Rust

let mut rules = engine::CrosswordRules { stacking_enabled: true, stacking_max_height: 5, forbid_same_symbol_overlay: true, stacking_scoring: engine::StackScoring::SumStack, ..Default::default() };

Notes

• Bonuses: letter bonuses apply to newly placed tiles; word multipliers multiply the whole word.
• When SumStack is used, underlying stack tiles contribute their base score (unmultiplied).
