A shikaku puzzle uses circled numbers to identify rectangular blocks. This puzzle includes empty circles and a few partial rectangle borders, but this is enough to deduce the complete solution to the shikaku puzzle.
The completed solution allows the solver to place the clue numbers into the circles, which are numbered. Converting the numbers into letters using A=1, B=2, and so on, and reading them in the order of the circles, yields the answer TOLLBOOTH.
