Information

Official rules · quick reference & legend
AI App · minimal 1v1 · current and future versions

This adaptation provides the Bulltricker AI engine, adjustable across several difficulty levels.

A game can be played:

  • either against the Bulltricker AI App (limited to a few levels in this free-to-use version);
  • or between two human players (minimal 1v1) sharing the same screen in turn — two people can thus face off on the same device.

The AI App offers a choice of colour and four levels: Discovery, Beginner, Easy, Apprentice. From Beginner onwards, the thinking time is adjustable (or unlimited); the Discovery level plays instantly.

As a guide, the Apprentice level in Limited mode, with the delay set to maximum, begins to show its strength. It can be even more formidable in Unlimited mode, at the cost of a little waiting and patience.

Future "IA Maxi" version

An "IA Maxi" version has been built. It carries the Bulltricker AI engine developed almost to its maximum, combining several algorithms and technologies.

This version remains undisclosed for now. It already includes several additional levels, the two most powerful being Master and Grandmaster. It accounts for trick-level counting, the repetition rules and the donjon — an unbeatable defensive structure as long as its configuration stays in place.

We are currently studying its release online. It will be playable for free, but progressively: a higher level only unlocks after you have beaten the current one. It is only a matter of time before you can face it.

Online "player versus player" version

In parallel, we are preparing the development of a true Player versus Player mode, in real time and online. Two formats will be offered:

  • Training: to practise freely, against other players or against the Bulltricker AI engine — with no impact on your rating.
  • Official (ranked PvP): games in which each player puts their true playing strength on the line, every result moving their rating.

For this rating, we have chosen the Elo method — the benchmark rating system in the world of two-player games, born in chess and today adopted by countless games and sports.

Thank you for your patience — we are delighted to finally share this game with you.
