Tapa-two too much: Subtract some values from some(or all) of the digits in some(or all) clues,such that in every horizontal row(containing atleast one clue) ,a total value of 2 is deducted. No clue can be completely reduced to zero,though some digits can become 0.Then solve the resulting tapa.
Pencilmarks Tapa:Some letters are placed as clues.Each letter appears in three places in the grid.Each time,it has a different value(which can be found from the mapping provided).
Tapa fusion: Choose some non-overlapping 2x2 squares(containing atleast one given) and merge the four cells of each of these squares to form single 2x2 clue cells.All clues in those four cells will be merged to make a single clue.For example,if (1,1) and (2,4) are the individual clues,the merged clue will be (1,1,2,4). The resulting grid can contain only the merged 2x2 clues.
New-style tapa: Some tapa-like clues outside the grid indicate the lengths of blocks of diagonally adjacent shaded cells in the corresponding diagonal.
