Collect one postcard per local calendar day from a rotating catalogue of 20 designs. Open Postcards, choose “Today’s postcard,” then “Open my postcard.” The offer follows the date on your device. Refreshing does not offer another design for the same day.

How to collect your daily postcard

Biscuit’s postcards are illustrated keepsakes in Idle Cheeky Cat, our original browser game. They sit alongside your medal wall in Collection, but use a different collection rule. You do not need to earn a particular medal, finish a boss, buy a weapon or create an account to open today’s mail.

  1. Open the Postcard album directly, or choose Collection and then Postcard album in the game menu.
  2. Choose Today’s postcard to inspect the daily offer.
  3. Press Open my postcard. Opening the envelope is the collection action; simply seeing the offer is not.
  4. Check the status below the artwork. “Saved to your collection” confirms the browser accepted the collection. A warning that saving could not be confirmed has a different meaning.

Choosing “Not now” closes the offer without collecting it. You can return through the album later that same day. The automatic envelope can appear on Home after a campaign clear, but you do not need to wait for that prompt. Manual collection is available from the album, including when the first-play flow has kept the battle screen focused on the game.

There is no combat tradeoff to choosing a favorite postcard: cards do not equip as weapons or add Damage, Fire Rate, coins or Stardust. For those systems, start with Rebirth and upgrades or the weapon catalogue.

Daily rotation, repeats and missed days

The catalogue advances by calendar date, rather than by the number of times you open the game. With 20 current designs, the same design returns every 20 calendar days while this catalogue remains unchanged. It is not a random pull, a login streak or a reward for time spent shooting.

What changes the daily postcard?
SituationWhat to expect
Refresh during the same local dayThe same offered card; no extra daily claim.
Open after the local date changesThe card assigned to the new day.
Skip a dayThat day is not automatically collected. Its design returns on a later rotation.
Collect a design already in the albumToday is marked collected, but the unique-design total does not increase.
Rebirth or finish another levelThe daily offer still follows the local date.

At one new design per day, collecting on 20 consecutive local calendar days covers the current catalogue. Missing a day does not remove cards already collected. It can simply mean waiting until a missing design returns. The catalogue below shows the artwork for reference; reading this guide does not add any cards to your game album.

Using the album and keeping its records

The album shows a collected total and two filters: All cards and Collected. All cards includes uncollected slots marked “Still in the mail.” Collected narrows the view to owned designs. Select an owned card to see its full artwork and caption, then use “Back to collection” to return. A card can also show a sharing action; sharing is not an additional collection requirement.

Postcards are saved separately from combat progress in this browser. They do not sync to another browser or device, and the game’s downloaded save backup does not include them. Clearing site data removes the local album. Restoring a game backup can restore campaign records without restoring postcards that were removed. Read why postcards stay in their original browser before moving your game or clearing site data.

If the game says browser saving could not be confirmed, keep the current tab open and use “Try saving again” when offered. A card can be visible for this visit without being confirmed saved for your next visit. If only the image fails to load, the artwork retry action is separate from collection status; check the saved message before assuming the card was lost.

For a quick visit, collect the envelope and then choose “Let’s play.” The beginner guide covers the controls; the loadout guide helps with firing roles, and Levels & bosses lists the next campaign stop.

Daily postcard FAQ

Why did I not receive the next card after refreshing?

The offer is fixed for the local calendar day. A reload is not a new day and does not move the catalogue forward.

Do I need to log in or keep a winning streak?

No. This game’s postcard album uses local browser storage, and the daily card is independent of campaign wins.

Will Rebirth delete my cards?

The Rebirth action does not modify the postcard store. Clearing site data is different and can remove the album.

Is the Cloud Post card earned by clearing Cloud Post?

No. A postcard can share a setting with a campaign level, but its collection rule is the daily date rotation.
