Drop each tile into the column where it touches its equal power — 8, 2·2·2 and 2³ + 2³ only merge once you read them as the right power of 2 (2³ + 2³ makes 2⁴, not 2⁶).
Power Merge plays like the drop version of 2048: the board holds powers like 2³ and 2⁵, and the child drops the next tile into a column so it lands touching its equal power — two equal powers merge into the next one, and merges chain. The falling tile is written another way (8, 2·2·2, 2³ + 2³, 4·2², 2⁵ ÷ 2), so naming its power IS the move; it targets the classic slip that 2³ + 2³ = 2⁶ by showing that adding two equal powers just adds one to the exponent, and the last sector switches to base 3, where THREE equal powers make the next (3² + 3² + 3² = 3³). A wrong column only clutters the board, and a full board restarts with a fresh one instead of ending the game. Best for Grades 7–8.
