Alteil

A game of Alteil usually lasts between fifteen and twenty minutes. Since the internet allows players to use virtual gameplay techniques, players are able to do things which they couldn't do using physical cards. For instance, players can have the same card from their deck in multiple files (files are groupings of cards that are used in a match), choose cards to use from the entire deck rather than drawing cards from the deck and using them a hand, and complex mathematics can be implemented without disrupting the pace of the game. Players in the game are referred to as Iczers (イクサー, Ikusā).

The cards are separated into four element like groups called Spheres of Influence. These spheres are individually called: Refess (リフェス, Rifesu), Lawtia (ローティア, Rōtia), Gowen (ゴウエン, Gouen), and Falkow (ファルカウ, Farukau). Cards of a sphere typically have similar strengths and weaknesses.

Inventor Spot states: "Alteil takes up where these games leave off, adding exquisite anime style artwork and an online dimension few RPGs can match!"

Nate Ming at Crunchyroll praised the "smartly-designed system and beautiful card art."
