  "If you want to know how much the gameplay is affected by the "
  "hyperbolic geometry in HyperRogue, this mode is for you!\n\n"
  
  "You can try many different geometries here. We start by gluing "
  "n-gons in such a way that k of them meet in every vertex. "
  "Depending on n and k, this either folds into a sphere, unfolds into a plane, "
  "or requires a hyperbolic space. The result may be then 'truncated' by "
  "replacing each vertex by a 2k-gon. Furthermore, you can play "
  "with quotient geometries. For example, the elliptic geometry is "
  "obtained from the sphere by making the antipodes be the same point, "
  "so you return to the same spot (but as a mirror image) after going there. "
  "Have fun experimenting! "
  "Achievements and leaderboards do not work in geometry experiments, "
  "except some specific ones.\n\n"
  "In standard geometry (truncated or not), you can play the full game, but in other geometries "
  "you select a particular land. Lands are unlocked by visiting them in this "
  "session, or permanently by collecting 25 treasure. Try Crossroads in Euclidean "
  "or chaos mode in non-standard non-quotient hyperbolic to visit many lands. "
  "Highlights:\n"
  "* Crystal World and Warped Coast can be understood as extra geometries.\n"
  "* Halloween is specially designed for spherical geometry.\n"
  "* To see the difference, try Hunting Grounds in Euclidean -- it is impossible.\n";
