Doolhof
Read full descriptionHide full description
Find your way through an ever growing maze. One problem though ... it's completely dark ... Luckily you are a blue wisp (a ball of light) and you can shine your way through the darkness to find your friend and fellow wisp in the other corner of the maze. On your way you have to avoid foes, use protection shields and look for other helpful items, but use them with care ... don't let them distract you from your goal! Blaze through the first levels with ease, but beware ... you will get lost ... Doolhof (the Dutch word for maze) is a quirky retro style maze game, playable from 4 to 94 years old, no learning curve, no language barrier & hours of fun. This app is completely free from advertising, no in-app purchasing, no signup, no registration, no subscription, no data collection. Just like the good old days!

Verdict
The clearest difference is update cadence: Rock Zapper at every 2 months against Doolhof's every 14 months. Doolhof's advantage is device support (5 vs 3) and iOS requirement (13.0 vs 15.0). On price, ads and in-app purchases there is nothing between them.
