Frozen Free Fall Snowball Fight has theoretically been around for a few years, primarily as a mobile game. Recently, it received a port to consoles with an extra multiplayer mode. It is not online, and it local only which actually makes things a million times easier.
The game is a simple match-three style game, and if you are familiar with Bejewelled, Candy Crush etc, then you'll pick this up in no time.
Realistically, you can just play this through from level 1 to around level 180 and pick up most of the achievements. I can't really explain much more than just match up at least three of one particular colour.
A good tip is if you are not doing so well, and are inevitably going to lose a life, you can hit your Xbox button on the controller, and quit the game. Head back into it, and your life will be intact.
It may also be worth noting that if you fail a level, and retry without quitting the game completely, the level does not randomize again. It sets itself out in the exact same pattern you previously had. In many ways this is advantageous as you can pre-determine your moves more efficiently.
The multiplayer aspect of the game is much easier to get your achievements on, as you can cheat. It's entirely up to you if you want to get another person and play it together, but it's much easier to do it on your own.
Get your other controller, and just collect the achievements without the need to worry.
Level 9 Note:
Level 9 in the game is quite possibly one of the key levels for obtaining most achievements. The way the level is set up is that you need to drop a few objects, but have a lot of moves to do it in. As not all coloured crystals are present in the game, it makes it very easy to create Windchills, Icebergs and Glaciers. You also get 2 free Glaciers to use each time you play.
The game is designed to take your money. It wants to shove its overpriced micro transactions in your face as much as possible. In fact when you are out of lives, it actually asks you TWICE if you want to buy more lives.
No level is impossible, but there are some which really push the boundaries of fair-play. Trying to keep your cool and not lose your patience is half the battle.
