Walkthrough

	Step 1 This is the start of the puzzle, we're given the <3>s as initial clues. Solve this puzzle for yourself at the same time.
	Step 2 There is only one way to fulfil these two squares 3 > 2 > 1.
	Step 3 This could be either 3 > 1, or 3 > 2, but we've already got the <2> in Column 2, so it must be 3 > 1.
	Step 4 In Row 1 the remaining square must be <4>. In Column 2 the remaining square must also be <4>.
	Step 5 As we've already got the <3> in Column 4 and the <4> in Row 4, there is only one way to complete these two squares, 2 > 1.
	Step 6 The only missing number for Row 4 is <3>.
	Step 7 The <1> in Row 2 can only go here (as there is already a <1> in Column 1 and Column 3).
	Step 8 The <4> in Column 4 must go here.
	Step 9 The <3> from Row 3 must go here (as there is already a <3> in Column 1).
	Step 10 The puzzle completes as both Row 3 and Column 3 have one remaining number. Which leaves the last <4> to complete Row 2 / Column 1.
	Step 11 The completed puzzle.
