Tips to solve

Are you stuck? Here are a few pointers to get you going. 

• Only 2 combinations of 3 are available at the start. Pencil those in. Unfortunately, no 4, 16 or 17. 
• Use the 45-rule to fill in combination 8 in TRRC (Top Row, Right Column).
• This allows you to use the 45-rule on combination 11 in TRMC (Top Row, Middle Column), which in turn allows you to use the 45-rule on combination 9 in MRMC.
• Use the 45-rule to fill in combination 10 in BRLC (Bottom Row, Left Column). Now you can fill in the 1 and 2 in MRLC.
• From here, you can at least pencil in all numbers in the Middle Column. Once you're done doing that, you will have filled in 14 definite numbers in that column.
• Focus on the BRbr (Bottom Row, bottom row) by using the row strategy, then on the BR as a whole.
