Sliding puzzles

Help

Three sliding block puzzles share one board. In Traffic you drive the red car out through the gap on the right, and each vehicle only moves the way it points. In Escape you slide the big block out through the gap at the bottom, and every block moves all four ways. In Tiles you put the numbered tiles back in order. One board is one round.

Press a block and drag it along its rail. It follows your finger, stops where the rules stop it, and lands on the nearest whole cell when you let go. A tap on a block with one move makes that move. A tap on a block with two or more lights it up and dots every cell it can reach, and a tap on a dot sends it there.

On the tile boards a tap on a tile in the empty cell's row or column pushes the whole row, and so does Enter on that tile. It counts as one move here. It counts as one move for each tile against the fewest, because the search behind the fewest slides one tile at a time. A board solved with those pushes can finish under the fewest. The 15-puzzle has no fewest, so there the page says only that the row moved.

Every board but the 15-puzzle carries a fewest that was searched for, not guessed. The 15-puzzle has about ten thousand billion positions and nothing here searches that, so it has no fewest and the result says so.

Hint points at the next move and waits for you to make it. It counts, and the result says how many you used. On the 15-puzzle the hint walks the mix back instead, and it says so. A round with a hint is saved to your statistics and counts as solved there, but it is not sent to the community comparison.

The result is the moves you made, the fewest the board takes, the hints you used and the time. The clock starts on your first move and pauses while the tab is in the background. Undo takes a move off the count. Reset and New deal start the board again from nothing.

The result says how you did on this board. It is not a speed record and it says nothing about any other board. Only a solved board is saved. A board you leave before it is done is not saved.

The statistics page compares rounds on the same board. Two boards are two tasks, so a five move jam never sits beside the ninety one move classic.

Name what blocks the target, then name what blocks the blocker, and move the last blocker first. Learn how to clear the lane
