Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“Getting a roguelike deckbuilder right takes a lot of player feedback. You can't balance the content, smooth out the rough edges, or make sure the game runs well without people actually playing it.
That's especially true of the balance between fun and difficulty. How hard a game can be before it stops being fun is different for everyone, and whether it pulls you in is something only you can feel. Early Access lets me work that out together with the people playing the game.”

Approximately how long will this game be in Early Access?

“My current estimate is about a year. If getting the game right takes longer, I'll take the extra time.”

How is the full version planned to differ from the Early Access version?

“I plan to add more rewards that keep each run feeling fresh, expand the ways players can take their decks in different directions, and add higher difficulty tiers for experienced players.”

What is the current state of the Early Access version?

“You can play the game from start to finish right now. Please see the “About This Game” section for details about what's currently included.”

Will the game be priced differently during and after Early Access?

“I plan to raise the price when the game leaves Early Access. If you buy it during Early Access, you won't have to pay extra for updates.”

How are you planning on involving the Community in your development process?

“I'll be reading reviews and following discussions on the Steam Community Hub. I'm especially interested in hearing what players think about the balance and any problems they run into.
Every piece of feedback matters. I hope each update makes it clear that I'm listening.”

About This Game

Hanafuda meets roguelike deckbuilding!

A roguelike deckbuilder built on traditional Koi-Koi rules.

Never played hanafuda? Don't worry.

The rules take minutes to learn. Putting it down is the hard part.

Simple rules

Play a card from your hand and take the matching month from the table. That's all there is to it.

High risk, high reward

Complete a yaku and you get a choice — stop, or call "Koi-Koi"!

Every Koi-Koi you call raises the stakes, and completing another yaku multiplies your score.

But if your hand runs out before you complete one, everything you staked that month is gone.

Yaku only hanafuda has

Brights — only five in the whole 48-card deck. Three of them turns a round around.

Akatan · Aotan — three red ribbons, three blue ribbons.

Inoshikacho — the boar, the deer, and the butterfly. Collect the animal yaku.

Hanami · Tsukimi — the sake cup meeting the cherry blossom, or the full moon.

Animals · Ribbons · Junk — complete them by count alone. Every extra card raises the score.

Pay the rent with hanafuda

Rent comes due every month. You pay it with the points you scored that month.

Whatever you can't cover carries over, and missing two months in a row means eviction.

One miss is a grace period — pay it back next month and you live.

Rent climbs as the year goes on. Survive the final collection in the twelfth month and you win.

Collect cards and relics to build a winning deck

Shop — spend gold on relics, open hanafuda packs, and remove the cards you don't want from your deck.

Relics — strengthen a suit, multiply your score, or rewrite the rules outright.

Unlock yaku — Godori, Chodan, and four month sets (Iris · Maple · Rain · Paulownia). Scoring hands that aren't in the base rules.

Level up yaku — raise the score of the hand you're building toward.

Features

20+ relics, 6 unlockable yaku, a shop that's different every run

A rent bill every month — one Koi-Koi can decide whether you survive it

Twelve months, about 30 minutes a run — made for deckbuilding roguelike fans
