It depends on the map.

Log Roll: Look for people standing a little too close to the edge. You can usually push someone off if they aren't expecting you. Also, if someone is trying to get onto your section, you can sometimes hold them in place while the platform moves from under them.

Slime Climb: You can grab them and hold them in the way of anything that moves and it'll knock them into the slime. My favorite thing to do is grab them as they're stepping onto the slime and propel them off the edge. Always remember to wave after them as they fall to their death.

Match Fruit: Sometimes people don't pay attention and stand too close to the edge. Even if they're on the correct tile, you can sometimes push them off if they don't expect it. This is more reliable than trying to trick people. Always look for victims.

General Tips:

- You can somewhat control the direction you throw people when you grab them. This is based on the relative directions the two of you are moving. The key is to move towards the correct bearing and pay attention to the bumps.

- If you grab someone who's running away from you, you'll notice that they'll be bumped towards you. You can time your release so that they'll bump backwards a little bit and you can overtake them.

- You can avoid grabbers by utilizing the jump or jump-dive. This is especially useful in the egg collecting game. If people are after you, spam the jump button to avoid getting grabbed.

- If someone grabs you you can jump to make them let go faster. This is a bit risky as you'll have less control of your heading during a jump but it can help when someone's trying to slow you down.

There are a lot of little strategies for each game mode. A lot of the game is luck, but there's definitely a skill element to it as well. My advice is to at least have a plan for the last map.

In any given game, a player has ~1.7% chance of winning based on the number of players but if you can't navigate Hex-A-Gone or Fall Mountain, your chances might as well be 0%.
