Remplir exactement dix pour cent

Based in Marcq-en-Barœul near Lille, Dix Pourcent is an independent game studio owned by 10 POURCENT. We design small proportion puzzles for Android in which the goal is always to reach exactly the right share.

One level asks for a glass filled to a tenth; another for a cake shared between seven friends; another for a garden that is exactly half in bloom. Each puzzle fits on a single screen and is solved with a few careful gestures.

There are no timers, no lives and nothing to buy. A gauge shows how close the player is, and a level can be retried instantly. Later levels combine two containers or two shapes, so the player has to think about one share in terms of another.

The puzzles are designed to be friendly to people who say they are bad at maths. Nothing is written as a formula; everything is shown with water, sand, fruit and light, and the satisfaction comes from seeing the right amount appear.

Every level can be replayed, and progress never leaves the device. We test each puzzle with players of different ages and adjust it when guessing becomes easier than understanding.

Levels come in themed sets such as the kitchen, the garden and the workshop. Each set teaches one idea, for example comparing two containers of different sizes, and the last level in a set mixes everything learned so far. Players who enjoy a challenge can aim for a perfect pour, where the gauge lands exactly on the line, while others can simply get close enough and move on. The art uses soft glass, water and paper textures, and a quiet soundtrack of pouring and dripping sounds keeps the mood relaxed throughout. New sets are added as they are finished.
