One move at a time
Check the sequence
For normal 8×8 play with row/column clearing. A recommendation for your visible pieces, not a prediction of the next tray or official score.
Try a board we can explain
Three small lessons.
Original practice boards, not numbered game levels.
From the game to a plan
Check. Compare.
Then place.
Recreate the position
Mark the occupied cells and choose all three shapes. A wrong square or a rotated shape changes the answer.
Compare legal sequences
The planner tries piece orders and placements. It favors placing more pieces, then useful space and cleared lines. If it reaches its search limit, it says so.
Replay each move
Use the highlighted squares and row/column labels to check every placement. After a three-piece sequence, enter the next tray.
