Your first few letters
Choose a space, then a tile. You can also drag a tile, or type its letter.
Adapted from the Gastronomy collection, with extra letters already in place.
A small move. A new possibility.
One letter opens up the next word.
Let the crossings guide you.
A letter can belong to two words. Place one, look again, and another possibility appears.
Try. Move. Find.
Return a tile to the tray, change your mind, or ask for a hint. There is room to explore.
A closer look
Your letters. On every screen.
The same pleasure of playing, from the palm of your hand to the big screen.

The pleasure of figuring it out
That little “aha”.
There is something satisfying about seeing a possibility become a word. These studies offer a way to look at that experience.
Ross & Vallée-Tourangeau · 2019
Thinking with letters
In a word-production task with seven physical tiles, Ross and Vallée-Tourangeau found only a marginal overall benefit of interactivity. Detailed analyses linked manipulation time to performance; verbal fluency also mattered. This is an exploration of a particular task, not proof that moving tiles improves cognition.
In Tilzl: make an idea visible by placing a tile, then reconsider it.

The moment it clicks
Danek and Wiley asked 70 people to explain 37 magic tricks. Pleasure, suddenness and certainty were central to their “aha” experiences. Incorrect answers could also feel like insights. The study concerns magic tricks, not Tilzl.
Our design reading: let the completed word remain visible, with a brief celebration.

A challenge you choose
Across four studies, Ryan and colleagues linked perceived autonomy and competence to enjoyment of video games. Their multiplayer survey also linked connection with others to enjoyment. These findings do not establish an effect of Tilzl’s modes.
In Tilzl: choose your pace, your difficulty, and whether to play together.

Inside the making
A game you can almost touch.
I wanted placing a letter to feel like a small, deliberate gesture. The details follow that idea.
Imagined and developed by Clément SauvageA material for every gesture
Ivory ceramic tiles, a sage felt tray and a plum ink. Movement and optional haptics give picking up and placing a tile a distinct feel.
Space to see the words
Fraunces and Hanken Grotesk, adjustable text, dark mode and an optional OpenDyslexic font. The app adapts its layout to iPhone and iPad.
A grid that holds together
The bundled grids are checked by a solver for a unique solution against the game’s dictionary. This verifies the puzzle; it does not guarantee that every definition is flawless.
Place a letter. Let the words take shape.
