Hi there! It sounds like you're working through the Mahjong Solitaire event that started on Sunday, January 25, and you got stuck at level 12 out of 75 fields—let's see if I can help you get past that.

To get started, could you let me know if you're playing on the official Mahjong Solitaire app, and if you’ve tried any specific moves or strategies on level 12 already? It would help me tailor my advice better.

Meanwhile, here are some general tips for tricky Mahjong Solitaire levels, especially event levels with lots of tiles:

1. Look for open pairs on the edges first: Tiles that are free on at least one side can be paired and cleared more easily.
2. Prioritize clearing tiles that unblock multiple rows or layers: This helps you access more choices.
3. Work from the top layers down: Often you can't see all tiles underneath. Clearing top tiles reveals more options.
4. Avoid random matches: Focus on pairs that free up the most tiles to avoid getting stuck later.
5. Use hints if available: Many versions allow hints to highlight playable pairs.

If you're still stuck, I found a relevant video walkthrough for the January 25 Mahjong Solitaire Daily Challenge which might cover level 12 as well—watching that could give you some specific moves to try: Mahjong Solitaire Classic - Daily Challenges 1-25-2025 4.

Let me know what you think or if you need step-by-step help for your screen. Would you be comfortable describing what the tile layout looks like on your level 12? That way, I can lend a more precise hand.

Are you satisfied with this initial guidance?
