This compact logical conundrum features a 5x5 grid into which the solver must fit the numbers 1 to 5 once per row and column. To guide you to the solution, there are 'greater than' and 'less than' symbols indicating the relationship between certain cells, and sometimes given starter numbers.

Solvers can get hints and check their answers via the menu options, and use pencil mode to sketch in the possible solutions for each cell. If they complete the puzzle quickly enough, they may get the option to post to the puzzle leaderboard.
