Standard Sudoku Rules apply to the final numerical layout.

Tired of standing in queues? While you wait, make your way through this queue. It begins in the top left corner and works its way to the bottom right, following the path of the grey lines which are joined together by killer cages so you don't make a wrong turn.

Digits in cages must sum to the total in the top left corner.

The grey lines in the queue are of four different types, which must be determined:

[1] Math: One digit on the line is the sum of the other digits. Digits may repeat if allowed by sudoku. Unlike Arrow Sums, the sum digit is not required to be at one end of the grey line.

[2] Thermometer: Digits rise from the bulb to the tip. Thermometers always rise following the direction of the queue, with the bulb coming first.

[3] Renban: Digits on the line form a set of consecutive digits, though in no particular order.

[4] Palindrome: Digits read the same from either end of the line.

All four types appear at least once in the queue, but no type is queued up twice in a row.
