You can always trap a single oncoming enemy in one hole, get his gold and run on over him without killing him. It is often a good idea to dig behind you and delay him further, but that might kill him. In some levels it is not a good idea to kill enemies.
You can usually trap two oncoming enemies in two holes, get their gold and run on over them, but this is dangerous if the enemies are separated by two or three spaces. Sometimes two holes kill one of the enemies and the other escapes and sometimes both escape. In KGoldrunner rules it is easier to trap two enemies and run over them, because they stay in the holes for longer.
It is nearly always impossible to trap three oncoming enemies and run on over them. You will have to kill them, dig and drop through the floor or simply run away.
Try to get all the enemies running together in one group. That way you will not get surrounded and you can do such fun things as collect gold while they run along behind you.
Sometimes you can kill an enemy with two holes, but it often takes three to nine holes to kill one to five enemies.
It is possible to kill an enemy with one hole if he is far enough away when you dig it.
In the “Traditional” game, you can trap an enemy permanently in a pit of brick or concrete. Stand near the edge of the pit on the opposite side to the enemy. As he approaches the pit, move down one square (to the level of the floor of the pit) and the enemy will usually run into the pit.
In some levels in the “Traditional” game, you can force an enemy to climb a ladder ahead of you if you stand somewhere above the bottom of the ladder.
In the “KGoldrunner” game, you can trap an enemy in a pit by getting him to fall from above you, then running sideways and digging out before he reaches you.
In the “KGoldrunner” game, enemies cannot run through dug bricks, so you can sometimes use them as a barrier or hiding place.
