task_games__tetris__line_clear_count

Contract

1. Domain: games
2. Scene: tetris
3. Scene id: tetris
4. Public task id: task_games__tetris__line_clear_count
5. Supported query_id values: single
6. Answer schema: integer_count
7. Annotation schema: bbox_map

Program Contract

Program: max(cleared_row_count(simulate_drop(board, rotate_translate(next_piece, placement)))) over legal placements; scene=tetris; scope=line_clear_count

Candidate set: the visible game board, pieces, tokens, cards, tiles, marked state, legal-move cues, result panels, and labeled options inside the line_clear_count objective scope. Operands: visible scene state and prompt-bound operands named by cleared_row_count, simulate_drop, board, rotate_translate, next_piece, placement, tetris, line_clear_count. Operation: evaluate max over the candidate set using the visible game state, rules, legal moves, comparisons, counts, simulations, or option-selection constraints encoded in the program expression; generation enforces a unique final answer. Output binding: answer uses the integer schema; generation binds a unique final answer. Annotation witnesses: annotation uses the bbox_map schema; the prompt/annotation contract defines the minimal visual witnesses. Query ids: single.

Reasoning Operations

Families: filtering, counting, ranking, state_update

Generation Notes

1. single is the only public query id; the task-specific prompt key is trace metadata.
2. Annotation maps board and next_piece to the rendered board and NEXT-piece preview boxes.
3. Scalar annotation checked: true.
