ZeroTier One for iOS allows you to join ZeroTier virtual networks as VPN connections on your iPhone, iPad, or iPod Touch. ZeroTier creates secure peer-to-peer virtual Ethernet networks that work anywhere. Skip the VPN hassles. Connect hybrid clouds, remote teams, and IoT devices directly with no hardware required. ZeroTier One provides virtual network endpoint functionality for iOS devices. Getting started takes seconds: Just tap '+', enter your network ID and name, and then click ‘join network.’ (Once a network is added you can also join it via the iOS VPN control panel. It will appear there as an available VPN connection.) You can only join one ZeroTier network at once due to an iOS limitation of one VPN connection per network extension app. The app allows you to add multiple networks but if you flip one to 'on' any others currently joined will disconnect. We value your feedback! If you encounter any issues or have suggestions for future improvements, please contact our support team through our website. Thanks for using ZeroTier! Clients for other platforms are available on https://www.zerotier.com/ and source code to ZeroTier's core engine can be found here: https://github.com/zerotier/ZeroTierOne

About

MJ101

Features
Read full description

MJ101 is a casual tile-based game inspired by traditional Mahjong-style rules. Instead of simple matching, MJ101 focuses on understanding how Mahjong combinations work through interactive play. The experience is built around three core interaction types—Chi, Peng, and Gang—which help form different tile combinations as you progress through each stage. Chi represents sequence building, where tiles connect in order. Peng represents matching sets of identical tiles. Gang represents a complete set that triggers a stronger clearing effect. By using these mechanics, players naturally learn how Mahjong-style patterns are formed in a simple and intuitive way. Each stage is designed as a structured scenario with a clear goal. Early stages introduce basic Chi and Peng interactions. Later stages gradually add more complex layouts where Gang combinations and multi-step thinking become more important. This creates a smooth progression where each level builds on what you have learned before. Features: Rule-based gameplay inspired by traditional Mahjong combinations Chi, Peng, and Gang mechanics explained through interactive play Step-by-step progression from basic to advanced patterns Clean tile layouts designed for clear visual understanding Scenario-based stages with different combination goals Short levels designed for quick play sessions Gradual introduction of new mechanics through gameplay Combo-based clearing system with chain reactions Offline supported for flexible play anytime MJ101 is designed as an easy way to experience Mahjong-style rules in a structured environment. The focus is on understanding how combinations are formed and how different moves affect the board, rather than relying on randomness or external systems. The visual design uses clean tile arrangements and clear spacing to make each stage easy to read. Every layout is carefully structured so players can quickly recognize possible combinations and make decisions based on logic and pattern recognition. MJ101 does not rely on chance-based systems. Progress is based entirely on understanding rules and applying them step by step within each stage. If you enjoy calm, rule-based gameplay that gradually teaches you how combinations work through interaction, MJ101 offers a simple and structured experience you can enjoy at your own pace.
