Quad Arena: card battles on a 4×4 board

Quad Arena

A tactical card battle on a 4×4 board. Take turns placing cards; every card has arrows on its sides and corners. Point at an enemy card and it's yours, unless it points back, and then the two battle. The loser flips to the winner's colour and takes the cards it points at with it.

  • A ladder of CPU opponents, from a gentle first match to a dragon's lair.
  • Quick matches against other players, or a private game with a friend's code.
  • Collect cards, level them up, and buy and sell them in the shop.
  • No ads. A match takes a few minutes.

TuneVpn: one tap to a private connection

TuneVpn

A VPN for Android that protects your connection with one tap. Your traffic is encrypted between your phone and the VPN server, so the Wi-Fi in a café, hotel or airport can't read it, and the sites you visit see the server's address instead of yours.

  • One big button: tap to connect, tap again to disconnect.
  • Free servers around the world, or let the app pick the fastest one.
  • Choose the protocol: Fastest, WireGuard, or OpenVPN over UDP or TCP.
  • Free every day: 15 minutes and 500 MB. No account and no ads.
