Isekai: Slow Life Codes (Active and Expired)
Last checked August 6, 2026 (UTC)
Mars Games rotates Isekai: Slow Life codes constantly, tying them to anime collabs and seasonal events, so this list moves more than most. I ran it against Try Hard Guides' July 20 check and the summer wave, iskfinal and iskmatch included, is still live.
Isekai: Slow Life codes are the gift codes Mars Games drops for events, anime tie-ins, and community milestones, and they pay out the crystals and buff items that keep your town growing while you are away for free Crystals, Fairy Bottles, Focus Candy, Basic Earnings Cards, Hire Cards, and the occasional elixir or crystal ore. Isekai: Slow Life is an idle town builder at its core, which means time and energy are the real currencies. Fairy Bottles refill the stamina you spend on story stages, Earnings and Hire Cards fast-forward your income, and Crystals are the premium money for summons and cosmetics. Codes are the only steady free source of all three at once.
Quick tip. spend the Fairy Bottles the same day you redeem them. Stamina overflow is wasted stamina in this game, and the code wave usually lands right before an event where the extra runs convert into event currency. Crystals you can bank, bottles you should drink.
Active Isekai: Slow Life codes (20)
All thirteen were confirmed working on Try Hard Guides' July 20 pass. Mars Games does not itemize every bundle in advance, so where a source only says free rewards, that is what I have listed rather than guessing at contents.

If a code comes back invalid, the event behind it probably closed. The sports-event wave, iskwcup, iskwball, iskmatch, and iskfinal, will be the first to go once the summer event wraps, so redeem those before the evergreen ones.
Expired Isekai: Slow Life codes
These are confirmed dead, including MYLIFE, which spent over a year on active lists before finally retiring this month. If a site still shows it as working, their list is stale.
| Code | Reward | Expired |
|---|---|---|
| MYLIFE | 200 Crystals, 2 Basic Elixirs, crystal ores, 10 Hire Cards, 10 Earnings Cards | July 2026 |
| tgsl2024 | 1,000 Crystals, 10 Fairy Bottles | before July 2026 |
| moonlit | 500 Crystals, 5 Fairy Bottles | before July 2026 |
| snowtime | 100 Crystals, 3 Fairy Bottles | before July 2026 |
New codes arrive with every collab and season, and the names telegraph the theme: konosuba and slimetensei came with anime crossover events, iskwcup and iskwball rode the summer sports events, and iskfinal closed that arc out. When the next collab is announced, expect a code named after it within days. Redemption is in game via your profile menu, one use per account, case sensitive. Event codes tend to die when their event ends, so the sports wave has a shorter fuse than the evergreen ones.
- Redeem in game: profile icon top left, then the Redeem Code option.
- Thirteen codes are live, one of the longest active lists we track.
- Codes are case sensitive, Idjkly starts with a capital i, so copy rather than type.
- Fairy Bottles from codes refill stamina, spend them the day you claim.
- Event-named codes expire when their event closes, grab the sports wave first.
How to redeem Isekai: Slow Life codes
Everything runs through the profile menu in game. Rewards drop into your mailbox, and the whole flow takes about ten seconds per code.
- Open Isekai: Slow Life and let your town load in.
- Tap your profile portrait in the top left of the home screen.
- Select the Redeem Code option.
- Paste a code exactly as written, these are case sensitive.
- Tap Claim and collect the rewards from your mailbox.
Redeeming on multiple devices? The code binds to your account, not the device, so one claim covers everything linked to the same save.
Isekai: Slow Life codes FAQ
What do Isekai: Slow Life codes actually give you?
The recurring payout is Crystals plus Fairy Bottles, with Focus Candy, Earnings Cards, and Hire Cards rounding out event bundles. Crystals are the premium currency for summons, and Fairy Bottles restore the stamina that gates story progress, so both matter at every stage of the game.
Why does the reward just say free bundle for some codes?
Because Mars Games does not publish the contents for every event code, and I would rather tell you that than invent numbers. The bundle reveals itself when you claim it from the mailbox, and historically the event ones land in the same range as the crystal codes.
Why is my code invalid?
Either the event behind it ended, you already claimed it on this account, or the capitalization is off. That last one bites more than you would think here, since most codes are lowercase but Idjkly is not. Copy and paste beats typing every time.
What are the konosuba and slimetensei codes about?
Anime collab events. Isekai: Slow Life runs regular crossovers with isekai anime series, KonoSuba and That Time I Got Reincarnated as a Slime among them, and each collab ships a code named after it. They tend to outlive the collab itself, which is why two slime codes are still active.
How often do new codes come out?
Roughly monthly, pegged to events rather than a calendar. A new season, a collab, or a community milestone each brings a code or two, and the summer sports event alone produced four. Checking back at the start of each event banner is the reliable rhythm.
Is there a level requirement to redeem codes?
No. The profile menu and its redeem option are available as soon as the tutorial hands you control of the town, and claiming early is smart since the stamina items stretch furthest in the opening chapters.
