About this app

No.9 is an attempt to transport you to a tranquil puzzly vacuum, a gallery of geometric forms and figures that evolve in harmony with a serene, slow-paced rhythm, inviting deep relaxation and contemplation. Your journey involves synchronizing diverse elements in both form and time.

Consistent with all my projects, this one also features no scores, no advertisements, no in-app purchases, and does not collect any data - just relax.

Featuring a wonderful soundtrack created by: Bartłomiej Kołaciak

★★★★★

another great minimalist puzzle game from the master of the genre, rainbow train. Very zen puzzle. A MUST buy at such an affordable price too! The goal of the puzzle is very intuitive and I figured it out in 30 seconds via trial and error. The puzzle involves arranging abstract shapes until the design they form, matches the abstract design provided. simple and fun.

★★★☆☆

The sheer amount of creativity that was required to design this game is remarkable. It's a really nice concept. In the first session, I made it until the two triangles with white/black lines and which are rotating on themselves. When I reopened the game to continue this morning, my progress was lost... I was back at the first level, and the manual level selection doesn't let me pick any further level. It goes without saying that it's a deal-breaker. When this will be fixed, solid 5 stars.

Superlative as always. A smaller game than the others by Rainbow Train, and while it's less 'cute', this is a very clever, very tricky-sometimes puzzle game unlike any other. It uses unique spatial mechanics, as puzzle elements. It gradually gets difficult, so you always have a learning curve that suits your play as you learn new elements. I always wish for more levels than exist though, because the games are always so fun.

Every time this publisher makes a new game I buy it, because every single game they've made so far has been pretty decent, and this one is no exception. Very simple premise, a bit like those web page CAPTCHA tests, but fun: jiggle around the components of an image until it matches the target image. The levels start very simple but become progressively more complex in interesting ways as you progress.
