Fill in the 100 squares with Russian cities based on the categories in the top row and the federal district given in the cell. For example, if you are looking at a cell with ‘Siberian’ in its row, and ‘Starts With O’ in the column, that cell can be filled in with ‘Omsk.’

Federal districts are not official divisions but can be seen here: https://en.wikipedia.org/wiki/Federal_districts_of_Russia
Breaking it down into the 80+ Federal States would’ve made the quiz too difficult.

Occasionally a cell may not have a qualifying answer, in which case it will appear blank and be a gimme.

hugequiz Premium members will see missed answers in red – they will be the largest city which qualified in each cell.
