i think its not otherwise it would have been mentioned.
Connectivity rule is applicable only for shaded cells :) |

No. The rules are the same as in normal LITS.
For some examples (Inversed LITS):

Yes.
The base rules are - When two “shapes” (tetrominoes formed by a group of 4 continuous cells) in adjacent regions
share an edge, they must not be of the same type, regardless of rotations or reflections.
In LITS, the shapes must be formed by shaded cells within a region and in STILO, by unshaded cells, but in both, the shaded cells must be connected throughout the grid. |

Akichiwake, r6c3 is not 9 but 7?
Syuma, why mustn't two cells at the lowest and left be passed? |

Sorry, I had a mistake for Syuma's rule. Please forget. |

For Akichiwake, there is this line in the rules - There need not be an area equal to this value, the only restriction is there can be no area larger than the
value connected within the region.
The region can basically work without any number but I put in the 9 to illustrate this sentence. The number just shows that there cannot be a white area larger than that. |

Location: Germany | Whee, some seriously other-universly types here. When I saw the Heyawake variant rules I thought at least it can't be as weird as Hayeweka, but it feels almost as twisted when solving. Thanks for the practice puzzles, by the way! (Is that Kakuro de Ni-keta insanely hard by any chance?) |

I think that type is inherently gonna be hard most of the time, unless the author makes a real effort towards simplifying things (giving more two-cell sums, etc. in the layout, or obviously low sums, neither of which "that" Prasanna did here extensively  ). But yes, this one's a bit hard, and good practice for the high pointer on the test, I feel.
Also, hope you have the changed version with the 40 sum in R2. Just checking to make sure. |

A lot of truly original puzzle ideas, and they were a lot of fun. Unfortunately there was not enough time to even start many of them, so it seems some of the effort was wasted. I always intend to finish them later but it doesn't always happen. I prefer the marathon/timeless format. The speed demons will still win (with their bonus points) but other solvers will get a chance to try all the puzzles. |
