Memo Forms vs Boltfall
Price, ratings, monetisation and update history for both games, side by side โ with what reviewers say about each.
Memo Forms
Read full descriptionHide full description
Visual memory game with simple geometric figures and icons. The board consists of several fields (depending on the board chosen) and each one of them hides a form. The idea is to open pairs of fields that are the same. When the two open fields are the same, they stay open and change to green. If they are not the same, the cells change to red and close again. You have to get all the fields of the board left open in the shortest time possible. The app will help you develop your mind by improving and training your visual memory. The game is perfect for everyone, both for the youngest who are developing their memory, and for adults who need to stay mentally fit.
Boltfall
Read full descriptionHide full description
Every plate hangs on its bolts. Unscrew them in the right order and the steel comes crashing down. Sort colours into a three-slot holder โ three alike clears it, one wrong bolt jams it. Easy to start, genuinely tricky to master, and satisfying every single level. HOW IT PLAYS โข Tap a bolt to unscrew it. Free every bolt on a plate and the plate falls away. โข The holder has three slots. Three bolts of one colour clear a set. Mix colours and you jam. โข Deep bolts need several full turns โ commit to one and it reserves a slot. โข Covered bolts hide under layered steel. Drop the plate above to reach them. WHY YOU'LL STAY โข 150 hand-tuned levels across six workshops, from Toolbench to Foundry โข A real difficulty curve: think two moves ahead, not just match colours โข Undo, hints and boosters when you're stuck โ never pay-to-pass โข Short levels, one-hand play, works offline โข Colour-blind friendly: every colour has its own head shape No forced video ads. Ads only play when you ask for a bonus.
