Based on the game High Performance #1, written for the 48. The screen is divided into 9 rectangular parts (3*3), and each digit (1-9) corresponds to a random combination of rectangle that will be blacked out. From a white screen, you have to blacken the 9 zones. To add to the challenge, if one or more areas of the screen are already blackened from the combination of the number played, they become white again.
A Doom level viewer. Does not have any monsters or game-play, but lets you walk around the maps in the shareware version of Doom. A port of 
Recreates the classic Mario experience on the G2, with infinite procedural levels (levels 3+ are randomly generated), realistic physics, Goombas and Koopas, powerups, and more.
The classic text adventure game, Hunt the Wumpus, in Python ported to the HP Prime. HP Prime firmware with Python required.

Number guessing game.
JezzBall is an arcade-style game, written primarily in Python with a few snippets of PPL code. The objective is to fill at least 75% of the rectangular playfield by launching splitters that divide the space. Balls bounce around the area, and if a splitter comes into contact with a ball while it's extending, the splitter is destroyed and you lose a life. When a splitter successfully divides the area into two parts, the region without any balls gets filled, bringing you closer to your goal. With each new level, splitters get faster and more balls appear on the playfield—steadily raising the challenge and testing your timing and precision
Another implementation of the Game of Life. Presently there are three pre-canned starting patterns and the app only renders the first 50 generations but it is a start..

It has survival mode (hunger, day and night, tools and armor to craft, a crafting table, a furnace, animals by day and monsters by night), creative mode (every item at hand, and you can fly), saved games, custom keys, and a built-in tutorial.
The graphics are original, drawn for the calculator.
Pseudo-3D racing game in the spirit of Out Run (Sega, 1986), written in Python. Five stages to cross in one go — countryside, desert, city, mountains, Miami Beach — on a road made of projected segments: curves, hills that hide what lies behind them, roadside scenery, twenty-four traffic cars, a day / night cycle with headlights, and a clock to win back from checkpoint to checkpoint. The text is the arcade cabinets' own: a bitmap font with a gradient and a drop shadow.
An Othello-Reversi program written in HPPL for the UI and in Python for the engine. It manages 4 phases of the game: the opening with more than 400 lines in the opening library, the midgame with an evaluation function based on 8 different factors, the WDL (Win-Draw-Loss) phase where the program searches for a winning line but does not care about the extent of the victory, and the search for the best final score.
(
Outrun style racing game, with amazing graphics, just like the old Sega game. Runs even better on the G2, with a higher frame rate and more draw depth.
Operate a remote-controlled bulldozer to clean up abandoned military warehouses packed with radioactive waste. A challenging puzzle game available in 8 languages! Looks similar to Sokoban but is actually fairly different. There are four kinds of objects: blue cold waste (after pushing it, it will roll until it hits a barrier), red warm waste (comes from a combination of two or more cold waste and cannot be moved), animated red critical mass waste (cold waste or warm waste can change into critical mass when it touches the critical mass), and boxes (you can push them and they will not roll).
Reversi (aka Othello) port for the Prime, featuring two-player mode and AI opponent support. Designed with a focus on graphics and animations.
Clear the board by selecting groups of adjacent circles of the same color. The points for a group increase with its size.

Card game of Spider solitaire.
The beginning of an implementation of an adventure game, but never finished. Maybe somebody would like to finish it, or at least look at the source code for inspiration.
This is a Sudoku editor/solver for the HP Prime. The GUI is a bit rough, but serviceable. Allows you to select the grid size (4x4, 9x9, or 16x16), clear the grid, and solve the problem, showing trivial hints. Includes some demo problems.
Another Sudoku solver, which uses two simplest techniques for finding the correct number: naked single and hidden single. If the sudoku is still unsolved, then depending on its current state, you choose one of three paths the brute force solver can take.
A set of tools for working with Sudoku, allowing you to play the game, solve the game, or make the game.
A simple side-scrolling platformer/tunnel hybrid where you control a bouncing ball, guiding it to the end of each level. Challenge lies in getting through narrow areas or climbing stuff without bouncing back, and it gets progressively harder to do so as the game progresses. The game features physics, randomized levels, animated graphics, multiple themes to make the game look different, smooth scrolling and parallax backgrounds. Try to get as far as possible as fast as you can without running out of time to get the highest score! For speed reasons, a G2 HP Prime is recommended. Version 1.02 (by Piotr) improves performance, necessitated by a slowdown caused by a bug in the September 2026 firmware.
T-Rex game modeled after the one in Google Chrome. Now fixed to run on the current firmware version.
Clone of Tetravex, originally included in Scott Ferguson's Windows Entertainment Pack 3, written in Python.

This is a port of "The Valley" game to the Prime. The original version was printed as a program listing in the April 1982 edition of Computing Today magazine for the Commodore PET.
Yes, this STG is called There. It’s a shooting game made in MicroPython. The game has a simple plot and animations, with a moderate difficulty level — at least I can barely clear it myself. It supports two control schemes: arrow keys or number keys. You can switch between them in the in-game settings.
Simulates rolling two six-sided dice.
Simple Tic Tac Toe game.
The developer wanted to learn about the miniMax algorithm, so he wrote this tic-tac-toe game and implemented miniMax so you could play a game against your Prime, with a full touch screen interface. It checks through 7! (5040) possible moves to make its move.
A fun and very exciting 2D Minecraft game, with infinite terrain and saving and loading. It only has creative mode right now.
Tower of Hanoi game that allows you to enter a challenge time, and calculates the average time per move or enter an average move time and calculate how long a practical activity with real objects will need. It implements the minimum 3-towers solution to the problem. It lists the required moves in lists L1 (from) and L2 (to). There is no animation of the contents of each tower.
Simple implementation of the Towers of Hanoi game.
Make the ball jump down the track without falling off the edge. Fun! An early work in progress. Has many optimizations since the earlier versions.
Modeled after the game board in the 1950s-1980s television show Treasure Hunt. Presents you with 12 boxes, one has $50,000. Select a box by just tapping the screen. You will then be presented with a sure thing. A choose box will be presented where you make your choice to take the sure thing or take a risk and open the box. Good luck!
A two-layer game where you must avoid hitting the opponent's trail.
This is the official release of the Prime port of the 39gII Tunnel clone written in BASIC, now adapted for the larger screen and color display. This new version adds speed throttling to ensure that the game runs as close as possible to the same speed as the original Prime on both the emulator and G2 hardware revision of the calculator. It is probably the first ever game ever made available for download for this calculator model. It isn't meant to show coding skills, especially considering the game was made before the author's knowledge of the DIMGROB_P and BLIT_P commands (although an intro transition using them was added afterward), but as you'll see on-calc, even if the entire screen content must be refreshed every frame, it still gets a high frame rate, because of how incredibly fast the calculator is, even with redrawing the entire screen rectangles and score text every frame. As for the multicolor and 3D-ish text effects, they are possible because the HP Prime lets you use text with no background, so all you have to do is superpose multiple copies of that text, gradually changing its color and position through a FOR loop. This also lets you use bold text. To play, just use the UP and DOWN keys and quit with ON.
The ultimate version of a popular memory game PAIRS. Human vs. Computer, Computer vs. Human, Human vs. Human, 4 difficulty levels: Sclerotic, Smart Kid, Superior, Unbeatable. Playable on the touchscreen.
