## What is Line?

Line-3 is a futuristic take on Picaria, a traditional board game of Native American cultures. The goal is to get three in a row, as in Tic-Tac-Toe, but Picaria offers more variety and tactical depth. The rules are simple:

1. Drop Phase: Tap to place your 3 stones on any of the highlighted pins
2. Move Phase: Slide your stones to a free pin to form a line of three

Line-3 packs Picaria's mechanics into an exciting high-score based game with varying AI difficulty over 15 rounds, and a stunning visual presentation.


Features:

● Easy to learn and play, yet challenging to master, with quick and casual game rounds
● Adaptive AI with three difficulty levels, indicated by varying color themes
● Beautiful soft illumination from randomly generated lighting setups
● Realtime ray tracing, thoroughly optimized for the latest generation of iOS devices
● Premium app, free of any ads and in-app purchases

Line-3 is the first mobile game to take full advantage of ray tracing, a demanding illumination technique that is often employed in major film productions.

## Key features

- Futuristic Picaria gameplay
- Strategic stone placement and movement
- Adaptive AI with 3 difficulty levels

### 1/5 — Não comprem

*2025-09-30*

Pessimo. Não explica nada. Imagem pessima. Vou pedir meu dinheiro de volta

### 4/5 — Multiplayer Would Be Cool

*2024-07-28*

You should add multiplayer. And it would be nice if the bot also had a score. This Is a pretty good game.

### 4/5 — Beautiful

*2022-02-13*

Not as good as the pictures but still extremely realistic and worth a try, the game is slightly difficult but easy to learn

### 1/5 — OVERCHARGED. PRICING FROAD APP. DON'T PURCHASE

*2019-05-20*

Recently I'd made a purchase of your app LINE-3 on my iPhone X. While purchasing the price of the app being shown was INR 9/-
But I'd been charged INR 76/-. 
It's worth eight times of the price you are showing of your app. 
Why this has happened. Please provide me my refund ASAP.

**Developer response:** Sorry to see that you ran into an issue. The payment process is fully handled by Apple, it is not possible for a developer to charge more than the displayed price. I recommend to contact Apple and request a refund.

### 2/5 — Need landscape view

*2019-05-11*

Could you possibly make your game landscape accessible? I play 99% of my games on my iPad Pro 12.9 2018 & it’s in a fixed leather sleeve, which is difficult to rotate.
Brilliant game though regardless.
