Your favorite Roll-and-Write games are now always at your fingertips! Launch and play on your smartphone, tablet, or laptop anytime, anywhere—even when printing sheets isn't an option.

A great solution for board game designers: test new concepts and check game balance on the fly in a convenient digital format.

KosmoPNP is a highly flexible digital playmat designed specifically for Print-and-Play (PnP) players and designers. Load your favorite game sheets, configure your dice pool, and play directly in your browser on your PC, laptop, or tablet - completely clutter-free.

Core Features:

  • Dynamic Multi-Sheet Layout: Load up to 12 sheets simultaneously (main boards, tech trees, or character sheets). Add, remove, resize, and arrange them on the fly mid-game.
  • Smart Drawing Toolset: Smooth pen with adjustable thickness, translucent highlighters, an eraser, and Quick Stamps (✔️, ❌, ⭕) that automatically snap to your game’s grid.
  • Advanced Dice Tray: Roll any combination of polyhedral dice (d4 to d20), add flat modifiers (+/-), lock specific results (Yahtzee-style), and track your history via the Roll Log. Drag dice directly onto the board!
  • Interactive Tokens & Counters: Track health, resources, rounds, or victory points seamlessly without typing numbers or writing by hand.
  • Custom Layout Presets: Hide tools you don't need and lock size elements to prevent accidental changing. Once you find the perfect setup for a game, save it as a preset file and share it with your friends!
  • 100% Free & Browser-Based: No ads, no paywalls, and zero installation. Lightweight architecture runs smoothly even on older devices.

How to Play:

  1. On PC & Laptops: Simply drag and drop stamps, tokens, and components from the left panel onto your sheet. Select and roll your dice pool, lock and reroll results in the tray, or drag individual dice directly onto the playmat.
  2. On Tablets & Smartphones: The adaptive interface shifts menus into clean tabs. The Tools tab activates a precision crosshair overlay - just drag the map under the crosshair and tap to place your stamps with pixel-perfect accuracy!

Future Roadmap

This app is a labor of love built by a solo developer for the tabletop community. Future updates include custom dice and card decks with shuffling mechanics.

Example Presets

To show off what the app can do, I’ve created a few presets for some awesome games. You can download them at the bottom of the app's page.

(Note: You can find the actual game sheets and rules on their official pages via the provided links).

  • A Simple Life: Uses only standard circle, cross, and checkmark stamps so you don't have to draw anything by hand.
  • 30 Rails: Only the pencil tool is enabled for drawing tracks.
  • Rolling Village: Uses custom stamps (house, water, tree, and square). They are kept small so they don't cover up the numbers on the board. A score counter is also included.
  • Fleet Signal Lost: My own epic sci-fi roguelike that utilizes a variety of different components.
  • Gem Cutter Pro: Use the highlighter to draw on the game board. The circle stamp is used to track gathered resources.

Let me know what other presets I should add, or feel free to send over your own presets to be featured on the page!
