Step 1: Start by looking for matching pairs of tiles that are free. Tiles are considered free if they are not blocked by any other tiles on one of their sides. You can select a tile by clicking on it. Once you have selected a tile, it will be highlighted, and its possible matches will be highlighted as well.

Step 2: Click on any matching tile to remove them from the board. Keep doing this until all the tiles have been removed from the board. You win the game once all tiles have been removed.

Step 3: Remember, you will only be able to match tiles that are free on at least one side. So, choose your moves wisely. Some tiles have different designs, but if they have the same animal character, they are considered a match.

Step 4: Be careful not to trap yourself by removing tiles that block other tiles. This is a common mistake beginners often make. So, plan ahead and make sure you don't block your path to the other matching tiles.

Step 5: In Time mode, you will have to beat the clock to score high. The faster you match the tiles, the more points you will earn. Keep an eye on the timer, and try to make quick matches without making mistakes.

Power-Ups:
Mahjong - Animal Solitaire comes with a variety of power-ups that can help you clear levels faster and score higher. Here are some power-ups you should know about:

1. Shuffle: If you get stuck and can't find any matching tiles, you can use the shuffle power-up to mix up all the tiles on the board. This will give you a fresh start and new opportunities to find matching pairs.

2. Hint: If you're having trouble finding matching pairs, you can use the hint power-up to reveal a matching pair. This will save you time and points, and help you clear the level faster.

3. Multiplier: As you progress through the game and earn higher scores, you'll unlock higher multipliers. These multipliers can multiply your total score, giving you more points to beat your friends' high scores.

Tips and Tricks:
1. Look for pairs on the outer edges of the board: Tiles on the outer edges of the board are easier to match, as they are not blocked on one side.

2. Clear the top layer first: If possible, try to clear the top layer of the board first. This will give you access to the tiles beneath and increase your chances of finding matching pairs.

3. Be patient: Mahjong - Animal Solitaire is a game of patience and strategy, so take your time and plan your moves carefully.

4. Use power-ups wisely: Don't waste your power-ups on easy levels. Save them for levels that are more challenging and require more strategic thinking.

5. Find matching pairs in the same row or column: If you're stuck and can't find any matching pairs, look for tiles in the same row or column. This will increase your chances of finding a match.
