Overview

Haptic Memory is a fully tactile version of the classic memory game. Instead of relying on colors or images, the tiles use raised geometric shapes that can be identified by touch alone.

The game was designed with blind and low-vision players in mind, but also works well as a sensory game for sighted players.

To support reliable gameplay, the project includes:

• 24 tactile memory tiles
• an optional but recommended tactile game grid to keep tile positions consistent
• a compact storage box with lid
• a Braille + Latin text insert for labeling (to be inserted at the front side on the box)

All parts are optimized for material efficiency and print reliability, without supports or exotic materials.

How to Play – Haptic Memory

Goal

Find as many matching pairs as possible using touch only.

Setup

• Place all tiles face down in the grid.
• Mix their positions before starting.
• Players should not look at the tiles during the game.

Gameplay

1. The active player selects two tiles and explores them by touch.
2. All players may touch and explore the revealed tiles.
3. If the tiles match, the active player keeps the pair and may take another turn.
4. If they do not match, both tiles are returned to their original positions.
5. The turn passes to the next player.

Important

• Tiles must always be returned to the same grid position if no match is found.
• The grid helps players remember positions through spatial orientation.

End of the Game

• The game ends when all pairs are found.
• The player with the most pairs wins.

Variants

• Cooperative mode: players work together to find all pairs.
• Solo mode: try to find all pairs in the fewest turns possible.

General print recommendations

• Material: PLA recommended
• No supports required
• Designed for standard 0.4 mm nozzles
• Tested on Bambu Lab printers

Detailed print settings are provided per part below.

Print recommendations - Memory Tiles

• Layer height: 0.12 mm
• Infill: 15–20 %
• No Supports
• No ironing (important for tactile feedback)
• No brim required

The low layer height improves tactile clarity of the raised symbols.

Print recommendations - Game Grid (optional but recommended)

The grid helps keeping tile positions consistent during tactile play.

• Layer height: 0.28 mm
• Slow first layer speed (~15 mm/s)
• Wall order: Outside → Inside

• Brim optional (5–8 mm if needed)

  Minor corner imperfections in the first layer are normal and stabilize in subsequent layers.

Print recommendations - Box

• Layer height: 0.20 mm
• Infill: 10–15 %
• No supports

Print recommendations - Lid

• Layer height: 0.20 mm
• Infill: 10–15 %
• No supports

• Printed flat on the build plate

   

Print recommendations - Text Insert (Latin + Braille)

• Layer height: 0.20 mm
• No ironing (important for Braille readability)
• No brim required
