This is just a proposal list of possible power ups and their effects. Not all will or need to b eimplemented. This involves considering game balance and player engagement. The probabilities need to ensure that more complex combinations are less frequent but more rewarding. Here’s a proposed table:

Power-Up Effect Description Combination Pattern Probability (%)
Anjana's Flame Clears a row or column 4 in a line 25%
Ojáncanu's Thunder Zaps random elements T or L (5 elements) 20%
Guerrero Cántabro's Rally Destroys surrounding elements 2x2 square 15%
Cures of the Cuelebre Transforms elements into health boosters 2x3 rectangle 10%
Breath of the Nubero Freezes a section of the board V shape (5 elements) 10%
Esbardu's Agility Allows swapping any two elements 2 consecutive 4-matches 8%
Ventolín's Whirlwind Swaps distant elements 2 straight lines (5 elements) 3%
Shield of the Trenti Temporarily prevents losing 3 consecutive color matches 2%

Each effect is designed to provide a unique advantage or impact on the game board, enhancing the strategic possibilities within the match-3 gameplay.

This table is a guideline and the percentages are hypothetical, designed to give rarer and more powerful combinations a lower probability of occurrence. Adjustments might be necessary based on actual gameplay data and player feedback to ensure a fun, challenging, and rewarding experience.
