What is this?

This is a simulator rolling the rare gacha (rare cat capsule) for Battle Cats. With the simulator, you can look into the future to predict and track your future rolling results.

1. Every game save has a seed number used to calculate the rolling result.
2. The seed number will only change if you roll the rare gacha.
3. We can observe the rolling results and figure out your seed for your game save.
4. The simulator is able to use the seed to calculate all the future rolling results.

⚓

How to use

First, you'll want to find your current seed. Watch the video or read the text explanation.

⚓

Seek the seed

1. Before you hit seek, follow these steps:
   1. Pick a gacha event (e.g. Ultra Souls or Uberfest). Use your rare (gold) tickets or cat food. Both work the same.
   2. Roll several times. Preferably 7 to 10 rolls. Record the results. The more rolls you made, the more accurate the result will be.
      • (Alternative) There's another strategy that you can just roll 5 cats, and it's very likely that it'll give you a wrong seed. That is ok, you can then roll the 6th cat, and check if it's matching your track or not. If not, put that 6th cat into the list and seek again. Repeat the process until you get an accurate result.
   3. Fill the results at seed seeking in the respective rolling order. Make sure you pick the gacha event you rolled with.
   4. If you made 11-rolls with a guaranteed event, or 15-rolls (3+5+7) with a step-up event:
      1. Don't fill your last guaranteed uber in the form.
      2. Fill the last 10 rolls without the last guaranteed uber.
   5. Avoid gacha events having repeated cats (e.g. Metal Busters or potentially collaboration gacha). If you did, you'll need to trial and error to find the correct one from the drop down menu picking the cats you rolled, because we can't tell which one you actually rolled. You can only try them one by one.
   6. Note that you only need to find the seed once. Following up, you can advance the tracks from there.
2. Understand the results:
   1. If everything is correct, you'll get the seed number, and two links (or three links if you filled 10 cats).
   2. The first link is using your starting seed for reference and debugging purpose, which shows the status before you rolled.
   3. The second link is using your last seed, which shows the status after you rolled.
   4. If you didn't roll in guaranteed events, you start at 1A in the second link.
   5. If you made 11-rolls with a guaranteed event, or 15-rolls (3+5+7) with a step-up event:
      • You start at 1A in the third link. 1A in the third link is exactly the same as 1B in the second link, because a guaranteed uber counts as a half roll, thus switching you to the other track.
      • If you made 11-rolls, you can also use the first link, which shows the status before you rolled, and click on the guaranteed uber link in 1A showing -> 11B, simulating your exact 11-rolls, leading to where you are now. The new page should be exactly the same as the third link.

⚓

Read the tracks

• Using the link, you'll see a table looks like below.
• Suppose you start at 1A, then your next roll with rare ticket or cat food will be the cat located in 1A. It's a rare cat (1A rare cat) in this case.
• Your next roll will be located at 2A, which is a super rare cat (2A supa cat).

⚓

Highlight rolls

• You can click on the cells, and it'll highlight the cats you'll roll out.
• Suppose we click on 2A supa cat's cell, and 2A + 3A will be highlighted in light grey.
• 3A rare cat will also be highlighted in zebra, indicating your next position after the rolls.

⚓

Advance the tracks

• You can click on the cat's name, which will simulate that you rolled to that cat.
• Following the above example, let's click on the cat's name at 2A (i.e. 2A supa cat) to simulate that you rolled to that cat. This will lead you to a table looks like below.
• You can see that you advanced two rows. Previously 3A rare cat was located at 3A, highlighted in zebra, now it's located at 1A.
• Your new next roll will be 3A rare cat located at 1A.
• You can see that the other track will also advance, meaning that you can only pick one in the same row.

⚓

Look up cat's data

• You can click on 🐾 beside the cat's name, which will show you the cat's data.

⚓

What is a guaranteed event

• There are two kinds of guaranteed events.
• One is 11 continuous rolls with 1500 cat food, which the 11st roll will be 100% uber regardless previous rolls, meaning that even if you rolled an uber cat earlier, the 11st will still be an uber cat.
• The other one is 3+5+7 (15) step up events, or increasing capsules, which you first use 300 cat food to roll 3 times continuously, and then 750 cat food to roll 5 times continuously, and finally 1050 cat food to roll 7 times continuously. In total 15 (3+5+7) rolls. Similar to 11 rolls guaranteed events, the last 15th roll will be 100% uber.
• Platinum gacha with platinum tickets for 100% uber IS NOT a guaranteed event. Only 11 rolls or 15 rolls can be a guaranteed event.

⚓

What is a guaranteed uber

• A guaranteed uber is the last roll with 11 or 15 rolls in a guaranteed event.
• Even if you rolled an uber as the last roll, if it's not rolled in a guaranteed event, it's not a guaranteed uber.

⚓

Read the guaranteed tracks

• Ubers listed on the guaranteed column are the guaranteed ubers.
• Guaranteed ubers will only be displayed if we're looking at a guaranteed event.
• Here if you make 11 guaranteed rolls, you'll get 1A ~ 10A and lastly 1A guaranteed uber, totally 11 cats.

⚓

Highlight guaranteed rolls

• You can also click on the guaranteed cells, and all the cats you'll roll out will be highlighted.
• Here we click on 1A guaranteed uber's cell, and 1A ~ 10A + 1A guaranteed uber are highlighted in dark grey.
• 11B will also be highlighted in zebra, indicating your next position after the 11 rolls.
• This is also indicated on the 1A guaranteed uber's cell, shown as -> 11B. Here we jump from 1A to 11B.
• This will lead to the next topic: Switch tracks.

⚓

Switch tracks

• Switching tracks will happen whenever you made any guaranteed rolls in a guaranteed event. Note that platinum gacha IS NOT a guaranteed event.
• Beside that you always stay on the same track, regardless you're seeing it as track A or B. See Tracks perspective for details about perspective.
• We already see an example switching from A to B above, let's see an example switching from B to A.
• Due to the offset, we jump from 1B to 12A.

⚓

Tracks perspective

• Track A or B is purely perspective. You're always on track A, and the other track is the alternative track.
• To observe the perspective, let's look at this example. Suppose we click on 2B rare cat's cell, highlighting the rolls:

• And then we click on 2B rare cat's name to roll to that position.
• We'll see that now the previous track B swapped to A, and A swapped to B.
• You're staying on the same track, because the next roll is still 3B uber cat and so on, but the perspective is changed and swapped.

⚓

Consecutive duplicated rare cats

• When there are consecutive duplicated rare cats in a row:
  • Before 8.5-, the game will just shift the second rare cat you'll get, avoiding consecutive duplicated rare cats. For example, suppose the game rolled two Tin Cats in a row, the second Tin Cat will be changed to Rocker Cat. You can predict the change by subtracting one to the original slot code, like Tin Cat (slot 9) becomes Rocker Cat (slot 8). Check Read the details to understand what is a slot code.
  • After 8.6+, the game will instead consume the seed again to roll another rare cat for you. As a result, it'll move you to the other track upon hitting into a consecutive duplicated rare cat. The reason you'll switch the track is exactly the same as rolling a guaranteed uber cat, that it'll consume the seed once, moving you half way forward, resulting track switch.
• Let's look at an example for 8.6+, where we have a consecutive duplicated rare cat at 4A, a Tin Cat can turn into a Pogo Cat.
• Assuming you're clicking on the cell for 4A, highlighting the path toward it.
• You'll see that Pogo Cat was highlighted rather than the Tin Cat, and your next position will jump to 5B instead of 5A.
