Avalanche is a fast winter skill game from Nitrome where you control a penguin riding a sled down a snowy mountain while trying to stay ahead of a huge avalanche. You need to maintain speed, jump over obstacles, collect fish, and reach the end of each Story level before the snow catches up.
The controls are very small, but the game becomes harder when several obstacles appear close together. I find it works best when you concentrate on maintaining smooth momentum instead of constantly changing speed. Avalanche also has an endless Survival mode for players who want to see how long they can keep going.

How Avalanche Works
Your penguin automatically moves downhill on a sled.
You control the speed and jumping.
The main objective is simple:
keep moving → avoid obstacles → collect fish → stay ahead of the snow → reach the finish
If an obstacle slows you too much, the avalanche can close the distance.
The Story mode contains 15 levels, while Survival mode continues until your current run ends.
Avalanche Controls
- D or Right Arrow: Accelerate
- A or Left Arrow: Brake
- W or Up Arrow: Jump
- Hold W or Up Arrow: Stay in the jump longer
Poki and the Nitrome Wiki both document this same basic control setup.
Speed Is The Main Part Of The Game
Avalanche is not only about avoiding objects.
You also need enough momentum to remain ahead of the moving snow.
Slowing down at the wrong moment can make the avalanche much closer.
That creates a balance between speed and careful movement.
Accelerate With The Right Control
Pressing D or the Right Arrow increases your speed.
This is useful when the route ahead is clear and you need to create more space between your penguin and the avalanche.
Within the game, maintaining momentum is one of the main ideas behind each level.
Braking Can Help With Timing
Press A or the Left Arrow to slow down.
Braking can make some virtual obstacles easier to approach when moving too quickly.
The important thing is not to remain slow for too long because the avalanche is still moving behind you.
Jump Over Obstacles
Press W or the Up Arrow to jump.
Holding the button keeps the penguin in the air longer.
That difference matters because some obstacles need only a short hop while others are easier with a longer jump.
Avoid Unnecessary Jumps
Jumping constantly can make timing harder.
If the path is clear, staying on the snow can make your movement easier to judge.
Use jumping when the course actually requires it.
Obstacles Reduce Your Momentum
Nitrome describes the game around avoiding obstacles while maintaining momentum.
That is one of the most important rules.
A collision is not simply a visual mistake.
It can slow your sled enough for the avalanche to gain ground.
Look Ahead On The Slope
Watching only the penguin makes upcoming obstacles harder to notice.
Try to keep your attention farther down the virtual slope.
That gives you more time to decide whether to:
accelerate,
brake,
or jump.
Fish Increase Your Score
Fish appear during your run and act as collectibles.
Poki specifically asks how many fish you can catch while staying on the course.
They give you another goal beyond simply reaching the end.
Do Not Risk A Run For Every Fish
Fish are useful for score, but completing the level is still the main objective in Story mode.
If one collectible sits in an awkward position, it can be better to stay on a safer route.
A clean run is often more useful than forcing every pickup.
There Are 15 Story Levels
Avalanche contains 15 regular levels.
Each one asks you to reach its finish while staying ahead of the avalanche.
The difficulty grows as the courses introduce more demanding layouts and obstacle combinations.
Story Mode Has Clear Finish Lines
Story mode is level-based.
That means each run has a specific endpoint.
Reach the finish before being caught and you complete that level.
This makes Story mode different from Survival, where there is no normal final finish.
Survival Mode Is Endless
Survival mode continues until the run ends.
The Nitrome Wiki describes it as a mode where you keep sliding away from the avalanche for as long as possible.
This gives Avalanche two different goals:
Story: complete levels.
Survival: last as long as possible.
Survival Mode Is Good For High Scores
Once the Story controls feel comfortable, Survival becomes a useful place to test consistency.
Because the course continues, small mistakes gradually become more important.
Fish collection also gives you another scoring target during the run.
The Penguin Rides A Sled
The main character is a penguin using a sled or toboggan.
Nitrome’s original 2009 announcement described the game around sledding down the mountain while trying not to be caught by a wall of snow.
This gives Avalanche its simple winter identity.
The Game Uses Pixel Art
Avalanche comes from Nitrome’s classic browser-game period and uses the studio’s recognizable pixel-art presentation.
The simple visual style makes obstacles, snow, fish, and the penguin easy to identify during quick movement.
The Avalanche Stays Behind You
The moving wall of snow provides constant pressure.
You cannot remain still or move too slowly for long.
That is why the game feels different from a normal downhill course where only the finish time matters.
Momentum Matters More Than Constant Maximum Speed
Going as fast as possible is not always the best answer.
Sometimes you need to slow slightly to set up a clean jump.
The useful pattern is:
accelerate on clear sections → adjust near obstacles → jump when needed → rebuild speed
That keeps the fictional sled moving without making every section feel uncontrolled.
Mistakes Become More Costly When Snow Is Close
A small slowdown early in a level may leave enough room to recover.
The same mistake when the avalanche is close can end the run.
That means your position relative to the snow should affect how carefully you approach the next obstacle.
Desktop Play
Poki officially supports desktop play.
Keyboard controls are compact:
Right or D: faster
Left or A: slower
Up or W: jump
There are no complicated button combinations.
Phone And Tablet Play
Poki currently lists Avalanche for:
- Desktop
- Phone
- Tablet
This is notable because the game originally came from the Flash era.
The HTML5 version allows the classic game to work across modern supported devices.
Avalanche Was Originally A Flash Game
Nitrome originally created Avalanche during the Flash browser era.
The Nitrome Wiki records the original Flash release as December 22, 2009.
Nitrome’s own development blog published its Avalanche announcement on that same date.
Original Release Date
The strongest original date is:
December 22, 2009.
This comes directly from Nitrome’s release announcement and matches the historical Nitrome Wiki record.
Avalanche Was Later Distributed More Widely
Nitrome announced a distributable version of Avalanche on December 6, 2011, allowing other websites to host the game.
That later distribution date should not be confused with the original 2009 launch.
HTML5 Brought Avalanche Back To Modern Browsers
Nitrome now lists Avalanche among its HTML5 games.
The Nitrome Wiki records the earliest known HTML5 availability in August 2021, while Poki also lists its own release and update as August 2021.
The clean timeline is:
Original Flash release: December 22, 2009
Distribution release: December 6, 2011
HTML5 and Poki version: August 2021
Poki Release Date
Poki currently lists:
Release Date: August 2021.
This is the current Poki HTML5 publication date, not the original release of the game.
Latest Poki Update
Poki currently lists:
Latest update: August 2021.
I did not find a newer verified Poki update date.
Current Avalanche Rating
Poki currently shows:
4.4 from 8,895 votes.
Because the number can continue changing, 4.4 from 8.8K+ votes is the cleaner format for publishing.
Who Created Avalanche?
Avalanche was created by Nitrome.
Nitrome’s own website still hosts the HTML5 game and lists it in its game catalogue.
The original credits recorded by the Nitrome Wiki include:
- Design: Jon Annal
- Programming: Aaron Steed
- Music: Dave Cowen
Other Nitrome Games
Poki currently links Avalanche with many other Nitrome classics, including:
- Bad Ice-Cream
- Bad Ice-Cream 2
- Bad Ice-Cream 3
- Twin Shot
- Cave Chaos
- Double Edged
- Final Ninja
- Skywire
- Swindler
- Cold Storage
- Cheese Dreams
- Blast RPG
Cold Storage Is Another Winter-Themed Nitrome Game
Cold Storage also uses an icy setting and comes from Nitrome.
Its gameplay is very different, focusing on platform movement rather than downhill sledding, but the shared winter presentation makes it a natural related title.
Bad Ice-Cream Is Another Nitrome Classic
Bad Ice-Cream is one of Nitrome’s most recognizable browser games.
It focuses on maze-like stages and fruit collection rather than downhill movement, but both games share the studio’s colorful pixel style.
Blast RPG Comes From The Same Developer
Blast RPG is also listed in Nitrome’s current catalogue close to Avalanche.
Its distance-based RPG mechanics are completely different, but both games come from the same classic browser-game period.
Avalanche Is Single-Player
The Nitrome Wiki records one player for Avalanche.
There is no verified local or online multiplayer mode in the original or current Poki edition.
For Mopoga, the correct field is:
Multiplayer: No, single-player
Common Avalanche Mistakes
One common mistake is holding maximum acceleration even when an obstacle is directly ahead.
Another is slowing down too much and allowing the avalanche to close the gap.
Players can also jump too early and land directly near another obstacle.
Another mistake is risking a good Story run simply to collect one difficult fish.
A Better Way To Play
Start by learning how quickly the sled accelerates and brakes.
Use clear sections to build momentum.
Look farther down the slope.
Slow slightly only when an obstacle requires better timing.
Hold the jump control longer when you need extra air.
Collect fish when they fit naturally into your route.
Then try Survival once the 15-level Story mode feels familiar.
A useful rhythm is:
accelerate → look ahead → adjust → jump → rebuild speed → repeat
Related Categories
Avalanche fits naturally into:
- Skill Games
- Winter Games
- Sports Games
- Platform Games
- Retro Games
- Pixel Games
- Penguin Games
- Single-Player Games
Poki currently places it under Sports, Skill, Flash, and Nitrome categories.
What Makes Avalanche Different?
Avalanche takes a very small three-action control system and builds the entire game around momentum.
You accelerate.
Brake.
Jump.
But behind you is a constantly moving wall of snow.
That means every obstacle affects more than the current moment. Losing speed can change how much time you have for the next section.
With 15 Story levels, an endless Survival mode, fish collecting, retro pixel art, and a modern HTML5 version, Avalanche remains one of Nitrome’s simple but memorable winter browser games
