aspirin

15-puzzle (sliding 1-15) for the Ontrol Orion (800x480), built only from stock Sedona kits (control, ontrolControl, ontrolOx, ontrolOrion), so it runs on the stock simulator.

App	What it does
aspirin.sax / app-ORION-aspirin.zip	Playable game: auto-shuffle at start, tap a tile next to the gap to slide it, SHUFFLE button, move counter, SOLVED!
aspirin_solver.sax / app-ORION-aspirin_solver.zip	Demo: shuffles 30 moves, then an auto solver plays one move per second until SOLVED! (it records the shuffle and replays the inverse moves)
aspirinV2.sax / app-ORION-aspirinV2.zip	Same game with fixed cells: nothing moves, each cell shows the number it holds on white, the empty cell takes the board colour

Run in the simulator

simulatorLauncher.exe → folder button → pick a app-ORION-*.zip → Start Simulator. The simulator is headless; to watch the screen run viewer\run_viewer.cmd (live view over SOX as guest, display only).

Build

python build.py          # gen .sax -> sedonac .sab -> launcher backup zips (all apps)
python verify_logic.py   # offline scan-engine model test of the game
python verify_logic.py --solver
python verify_logic.py --v2

gen_aspirin.py holds layout, colours, shuffle length (SHUFFLE_MOVES) and solver delay (SOLVE_DELAY); gen_aspirinV2.py generates V2. Paths to the Sedona install are at the top of build.py.

How it works

• Each tile is a PushButtonLabel whose x/y are linked from logic, so tiles move.
• Tile state = offset from home cell held in ADemux2 latches; blank cell = 3 - sum(offsets).
• A tile moves on a one-scan OneShot when it is next to the blank and touched (or picked by the shuffle); it latches the blank's cell and the blank follows automatically.
• Shuffle uses a logistic-map RNG made of Reset/Mul2 blocks; only legal moves, so always solvable.
• Solved = blank home and the weighted sum of tile offsets is 0 (rearrangement inequality).

V2 (fixed cells)

• 16 NumericSelectLabel cells; in = the number held (0 = empty), text list ;1;2;...;15;.
• backgroundColor is linked from logic: white for a number, board colour for the empty cell.
• State = 16 cell values in ADemux2 latches (boot loads the solved board). Blank position is derived from the values; a move latches 0 into the touched cell and its value into the blank.
• Solved = sum of i * value_i over cells 1..15 is 1240 (its unique maximum).
