Guide to Fast Move Mechanics

Last updated October 9th, 2019

Update October 9th, 2019 - Since app version 0.157.0, the mechanics for Fast Move registration have changed! This article and the site simulations have been updated to reflect those changes.

How exactly does Fast Move damage and energy work? In this article, we’ll go over the mysterious mechanics behind Fast Moves and how they impact gameplay.

Special thanks to FlarkeFiasco, GarretK19383, and TheMisterValor for bringing these mechanics to my attention and helping to compile and explore video evidence for all sorts of scenarios! This was an incredibly challenging puzzle to solve and it couldn’t have been done without their help.

Trainer Battles are broken up into turns. Each turn lasts 0.5 seconds. On a typical turn, each Pokemon can take one action - a Fast Move, a Charged Move, or a switch. Let’s take a look at how Fast Moves use turns and interact with one another.

Fast Move Duration

Each Fast Move lasts a certain number of turns, usually referred to as its “duration” or “cooldown”. Duration determines the amount of time between your Fast Moves. The timelines below illustrate different Fast Moves and their durations. Each circle represents a new action.

As you can see, a shorter duration allows more frequent actions.

Fast Move Registration

When you use a Fast Move, does it hit right away? Actually most of the time, no! Since update 0.157.0, Fast Move damage and energy always register on the last turn of the move. This means you will always have the energy from your previous move when you go to perform another move. The earliest time a move can register hasn't changed with this update, but it's now guaranteed to register at that time (previously it required another action happening on the same turn).

How does this all work? Check out to the table below for move durations, the number of turns that need to pass before the move hits, and example moves. Note that 1-turn moves register immediately on the turn they are used.

Duration Turns to Register Examples
1 0 Water Gun, Dragon Breath, Bug Bite
2 1 Counter, Vine Whip, Mud Shot
3 2 Air Slash, Fire Spin, Bubble
4 3 Confusion
5 4 Volt Switch

So what does this look like in action? The examples below show circles for when you tap to use a Fast Move and squares for when the move actually hits.

2-Turn Move vs. 2-Turn Move

Above we have a mirror match where both Pokemon’s Fast Moves have the same duration. Damage and energy register on the 2nd turn of the move, so play alternates between Fast Moves being used and Fast Moves hitting.

2-Turn Move vs. 4-Turn Move

Things play out similarly when the Fast Moves involved are even with one another. For example, Counter (2 turns) and Confusion (4 turns) happen in step so Confusion registers simultaneously with every other Counter. If you're a Confusion user, you're no longer stuck performing extra Confusions like you were pre-0.157.0.

1-Turn Move vs. 3-Turn Move

Battles against Pokemon with 1-turn moves will play exactly like before, since 1-turn moves previously registered their opponent's Fast Moves at the earliest possible time.

2-Turn Move vs. 3-Turn Move

Pre-0.157.0, 2-turn vs. 3-turn move interactions were complex and unpredictable. Now both moves register at steady intervals.

Sandbox Mode

When you enter Sandbox Mode, circle icons appear above the timeline to indicate when each players can use an action, like what’s been shown in the article so far. These appear at regular intervals like you might be used to, dictated by Fast Move duration. Click on the circular Tap icons to select an action for that turn.

You can select one of the following actions:

  • Fast Move - This player will use a Fast Move. This action will queue a new Fast Move to be registered as described in this article.
  • Charged Move - This player will use one of their Charged Moves. Note that a Charged Move will fail if a Fast Move that faints the user also registers on that turn.
  • Wait - This player will take no action on the selected turn.

Differences in 0.157.0

A big question is how have matchups changed? Are there any major new wins or losses? Here's a summary of what you can expect to find!

  • Flipped matchups will be ones that were previously very close with a difference of one or two Fast Moves, or IV's.
  • Damage and energy registration now happen at more predictable intervals. 3-turn moves will behave the same whether they're against a 1-turn move or a 4-turn move.
  • Pokemon are no longer overtapping, but that goes for their opponents as well. This generally benefits most Pokemon equally. Matchups involving a 3-turn move and a 2 or 4-turn move are the most suspectible to change because of how erratic move registration was previously.
