Chop X segments in one game or chop Y segments total.
The alternative to getting good scores is chopping a certain amount of segments. That is extremely tedious. A good player chops about 15000 segments in an hour of gameplay (yes, you can get more with uninterrupted grinding).

When you have 179 points, move into a losing position.

Play 3 singleplayer games in a row, showing consistently good scores.

Chop very quickly...

Start a game, chop as slowly as possible, keeping the bar close to the minimum, until you hopefully get the achievement.

Play 10 multiplayer games.

Win against 5 different players.

Keep playing Timbermill until you have enough wins.

Steam-exclusive characters: Tim Bear, Timb-nerd, Lucha Timbre, Gaben, Bruce Tree. See their entries below marked with the Steam icon.

Win against 10 oponents who have a much higher skill value than you. By how much? No clue.
This needs to be 10 different opponents.
WARNING: If you reach a high skill value before getting this achievement, you're screwed. Skill value can only go up.

Keep playing Timbermill and deplete your opponents' energy bar.

This achievement is very difficult to obtain, because good players will not let you win by speed consistently and you're likely to mess up, and players tend to fail before you can leave them behind in points.
You can play with a friend. The friend should do nothing and let you do your thing.

Requires at least 1 Angel and at least 1 Treedevil to be present, and all players need to be using these 2 characters. Awarded after a round ends.
Confirmed working in 2 player mode.

Chop X segments in one game or Y segments total.
Note that some of these unlocks require playing as Timber Claus so just play as that character for all the unlocks until you've gotten a 450 highscore.

This unlock consists of 2 parts. After scoring over 300 in singleplayer the description will change to what essentially means: score slightly below your highscore (but you will be able to see the exact range).
WARNING: pay attention to this if you're afraid you won't be able to match your highscore if it's too big.

Keep trying new characters and getting decent scores. This does not mean exactly 100.

Cycle through characters and lose as soon as possible.


The description updates to tell you how many more times you need to exit and start the game.


Not sure what affects this number, but hopefully after the specified amount of gameplay time this character will unlock.

This is quite difficult to do because both you and your opponent need to not fail and go at consistent speeds until you get 333 points.
Confirmed working in 4 player mode.



I'm guessing this means play 7 rounds without leaving the game, times 10

WARNING: This gets harder to do the higher your rank is


This is character is unlikely to be obtained, because good players will not let you regain so much advantage and bad players will fail before you can catch up. Also because of lag it's really difficult to get to exactly the minimum.
You can play with a friend. The friend should chop slowly until their bar fills up 100%, then stop and let you fill it up.
Confirmed working in 2 player mode.

Seems like this unlock was made with 2 player mode in mind ("lose twice then don't lose at all") but also seems to work in 4 player mode where it's even easier.
