## What is Hanafuda Koi?

Let's play Hanafuda (Koikoi), a traditional Japanese card game.

Koi Koi is a game of Hanafuda played by two players, where you match the cards in your hand (same month, same plant) with the cards in the field and make them your cards.

There is no limit to the number of rounds you can play, so you can continue playing until your LIFE runs out, and compete for the number of sentences you earn.

At the beginning of the game, you have 25 points, and every time you cut a card, you spend 1 LIFE. If you win a yaku, your LIFE is added to the number of sentences of that yaku.
If the CPU wins, your LIFE is reduced by the number of sentences of the role you won.

## Key features

- Traditional Japanese card game
- 3D graphics

### 1/5 — Can’t see my cards due to ad placement!!!

*2026-08-07*

I used to LOVE this app - this app is how I learned how to play Koi-koi, and where I fell in love with the game, to the point that I was inspired to design my own Hanafuda cards for friends! The layout is simple, the mechanics are good for beginners and still helpful once you’ve played for a while. I also love the paintings reward system, as a little incentive to level up your playing, as well as expanding the world of the app, and making the process of playing feel like it’s something bigger. 

However, recently I have become increasingly disappointed with this app. 

My first and long-standing issue is with the points: losing life points from BOTH losing a round AND every time you play a card is too much. It makes it impossible to extend a run on just small victories if your luck is bad but your strategy is good. A great koi-koi hand for you can only serve to buy you time, and winning a round can still drain you of life. Meanwhile, the computer can get one great hand and in one fell swoop end an otherwise promising run. 

This is frustrating, but I always treated it as an eccentricity of the app, and motivation to get better at the game.

Which brings me to issue number two: the app started showing me adds a while ago, during the games. This is annoying, but I understand it’s a part of how things are now. The developers need to make a living, I don’t begrudge them that. I wish I could buy an option to get rid of ads, I’d gladly spend money on that, but if that doesn’t support their work enough financially, I understand.

Until recently, the ads hovered over the opponent’s cards, in the top left corner of the screen. This was fine, since the opponent’s cards are turned over, so the ad didn’t block anything. Now, though, the ads appear in the lower left, directly over MY cards - making it impossible to view my cards LET ALONE PLAY THEM. The app is now unplayable!

To the developers - please fix this!!

I don’t want to move to a different app, but I’m not going to stop playing a game I’ve fallen in love with. Especially when this app is what drove that love in the first place!

### 1/5 — あほなん

*2026-08-07*

自分の手札の上に広告が載ってどうやって勝負するんや

### 2/5 — New Update

*2026-08-05, version 1.0.3*

The latest update has made the game SUPER unbalanced! It doesn’t feel like the perfect balance of skill and luck anymore. It’s a real shame.

### 1/5 — Was Good, Got Greedy

*2026-08-04*

A nice miniature version of koi koi with a decent life system until they added an ad banner right in front of your hand. Seriously?

### 3/5 — too many ads block flow

*2026-08-04*

well built game but obtrusive ads make it no fun

### 1/5 — Update ruined the game

*2026-07-30*

Until two days ago there were zero adds, and the resolution of the game was perfect and it looked and ran fine, now there is a splash add every screen change, an add bar at the bottom of the screen covering where your hand is during game play. And the resplution has made every card look terrible. Sad cause this game was great, think i might have even paid for no adds before the update.

### 1/5 — Ads have spyware

*2026-06-11*

Newly added advertisements in the game are contain links to spyware. I am uninstalling.

### 1/5 — 無理ゲーすぎておもんない

*2026-04-28*

運ゲーなはずなのにCPUの手札に毎回勝利に欠かせないカードばっかり、自分の手持ちにはカスを揃えるためのものしか来ず勝つのはまず無理
花札好きになったからやったのにやっぱり嫌いになりそう

### 5/5 — The best!

*2025-10-31, version 1.0.2*

I love this app! Hanafuda without any bloated ads or funny business! It is engaging and has a progression system! Its the best app in all honesty!

### 3/5 — Feels like playing against an entitled brat.

*2025-08-02*

The mechanics are solid, but the points system makes the entire thing feel like playing against an entitled brat who stacks the rules against you and insists that you have to keep playing until they win. As a result none of the achievements actually feel like achievements and the fun is sucked out of the whole experience.

There's way better ways to feel frustrated if you really want to.
