Color Drop : Moving Holes

The balls stay put. The holes do the moving. Every hole on the board is locked to its own row or column - drag it along that fixed track and it soaks up any ball of its color sitting in the way. Each hole shows exactly how many balls it still needs. Clear that number and the hole disappears, opening new paths for the holes around it. With tracks crossing in every direction, sliding one hole can block or free up the ones next to it. Plan your order carefully - the wrong move can trap a color in a corner with no path left to reach it. Hundreds of boards, from a handful of crossing tracks to dense grids where every slide matters. Clear every ball, one careful drag at a time.
