## What is Coin Line?

A brain training puzzle using money!
Merge coins to turn them into big money.
Five different currencies available: US Dollar, Euro, Japanese Yen, etc.

BASIC RULES:
Switch the coins wisely, and try to pile the same coins up.
For example, if you pile five 1 cent coins, they turn into a 5 cent coin. Two 5 cent coins turn into a 10 cent coin.
Every time the value change happens, the coins become 1 cent -> 5 cent -> 10 cent -> 50 cent -> $1. When five $1 coins turn into a $5 bill, and it disappears.

Coins are added from the bottom. Make a value change happen as fast as you can and erase the coins effectively.
When coins go over the line limit, the game is over.

As the value change happens, you gain the corresponding score. When you make a chain of value changes happen, you'll get the higher score!
Coin Line is a simple, yet profound, puzzle game that anyone can enjoy.

5 TYPES OF CURRENCIES:
The game supports Japanese yen, US dollar, euro, Pound sterling, and Chinese Renminbi.
You can change the currency at any time from the option screen.

SPECIAL COINS:
Sometimes a special coin with a certain icon will appear. If you eliminate these coins with a value change, the special effects, such as tripling the score and removing obstacle coins will be invoked. Aim for eliminating those coins!

UPGRADE:
According to the score you get, you'll receive coins. Use the coins to buy various upgrades at the shop screen.
For example, you can get upgrades to heighten the line limit or strengthen the effect of the special coins.
Upgrade yourself and aim for the higher score!

WORLD RANKING:
Support Game Center leaderboard rankings and achievements.
Complete against your friends or players all over the world!

### 4/5 — A favorite, some questions though

*2025-09-07*

I have had this since August of 2018. I am unsure if it has always had ads, but I don’t remember them initially and “restore” feature did not work, so perhaps they always have had ads? There is thankfully an inexpensive option to remove ads.

🟢Play in US coins, Euros, British Pounds, Japanese Yen or Renminbi. 
💚Addictive. But educational (requires knowledge of money and their values to play- for example if you stack five pennies on to each other, they become a nickel; if you stack two nickels on each other they will become a dime;  if you stack 10 dimes on each other they will become a $1 coin, if you stack 4 quarters on each other they will also become a $1 coin.) The goal is to stack the money until it becomes $5, at which point the $5 in coins will convert in to a five dollar bill and disappear from the game, allowing you more space to combine more money, as it continues to stack up all around you.  The money you stack becomes your score- it keeps adding up until you reach the top of the screen (think Tetris), at which point whatever money you have amassed is your total score for that game round, and that money is accumulated into your “bank” , combined with “money” you earned from all your other rounds, and it can be spent on expanding the number of columns you play with, the height of the game or things like boosts to help you play the game longer/ make you earn money more quickly. 
🛑Has (small, banner) ad across the bottom of the main screen [not during game play]) AND occasional video ads. 
🟡Ads can be removed with a small reasonable, one-time purchase of $2.99 - I would like to do this but:
⚠️Permissions are excessive and it's unclear if when you purchase the "remove ads" if they stop collecting your private data or not, because the developer's website AND privacy policy link to pages that say they are not secure “not private”, so I could not read them!!

### 5/5 — コインフィードって？

*2023-11-13*

赤い数字が0になったら下からコインが出る、はずが数字が残っていても上がってくるのはなぜ？
一定の行動で一列上がってくるのは決まりなの？
リラックスでターン数多いはずなのに😭？

### 5/5 — すばらしい！完全にハマってます

*2023-03-28*

何気なく始めたのですが、もう、爆ハマりです。子どもには両替の概念、理解につながると思います。

### 2/5 — まだ始めたばかり

*2022-01-29*

なので、単純に難しいなーと言う感想です。
コンボできるように並べれば良いのは分かってるんですが、私の頭が弱いのかうまくいかない…もうちょっと粘って遊んでみようと思います。

### 4/5 — 楽しいけど

*2021-05-20*

米ドル💲のゲームの時、5ドルより10ドルの方が小さいのが解せない。理解するのに時間がかかった❗️

### 3/5 — 面白いんだけど…

*2021-02-16*

バーがもう少し高いと嬉しいです。
もしくは何段階か選べる等でレベルがあるといいかなと思います。
私のスピードが遅いのかもしれませんが、下から上がってくるのが早くて、3段とか上がってくるのですぐ終わってしまって長時間は遊べません。
内容はおもしろいです。

### 5/5 — 😊

*2021-01-27*

楽しい、はまってしまいます

### 5/5 — iOSアプデ後開かなくなった

*2020-11-20*

とてもいいゲームなのに
アプリをタップすると同時に落ちる(T^T)
やっと数学者急級に上がったのに
なんとかして欲しい。

### 3/5 — 改善希望

*2020-10-04*

全消ししたときに、コインが自動で出てくるようにして欲しいです。

### 5/5 — 最高

*2020-06-12*

本当に面白いです
