Honestly, most people think they need a degree in game theory or a massive budget to design a home game. They don't. They really don't. You probably have a half-finished idea sitting in a notebook or a voice memo from three years ago. Maybe it was a drinking game, or a complex strategy epic, or a simple card game to play with your kids on a rainy Tuesday. Most of those ideas die because people overcomplicate the "design" part before they even have a "game" part.
Look at the history of modern hits. Cards Against Humanity started as a handwritten list of jokes on scrap paper. Magic: The Gathering creator Richard Garfield was a math professor who just wanted something to play between rounds at bridge tournaments. These weren't polished products on day one. They were messy.
If you want to design a home game, you need to stop thinking like a publisher and start thinking like a tinkerer.
The "Toy Factor" vs. The Rules
The biggest mistake? Starting with a 40-page rulebook. Please, just don't.
Games are about "the loop." This is a term used by professional designers like Reiner Knizia (who has designed over 600 games) to describe the core action a player takes over and over. You draw a card. You move a piece. You trade a resource. If that one single action isn't fun, no amount of lore or fancy art will save it.

Think about Jenga. The "loop" is just pulling a block. It's incredibly simple, yet the physical tension makes it work. When you sit down to design a home game, find your loop first. Take a deck of standard playing cards or some spare change. Can you make a game using just those items in five minutes? If you can't, your idea is likely too bloated.
Why complexity is your enemy
Complexity isn't depth. Beginners often confuse the two. Depth is when simple rules lead to complex outcomes (like Chess or Go). Complexity is when you have to check the manual every three minutes to see if a "Forest Troll" can move across a "Frozen Stream" during a "Blood Moon."
It's exhausting.
Prototypes Should Look Like Trash
I'm serious. If your first prototype looks good, you've wasted time.
Professional game designers call this "gray boxing" or "paper prototyping." Use index cards. Use Sharpies. Use buttons from an old shirt as player tokens. Why? Because if you spend ten hours making beautiful card art on Canva and then realize the card is boring, you'll be too emotionally attached to cut it.

You need to be able to kill your darlings.
Design a home game with the expectation that 80% of your first draft will end up in the recycling bin. Use masking tape on old dice to change the numbers. Draw a map on the back of a pizza box. This "lo-fi" approach allows you to iterate fast. Speed is everything in the early stages. If a mechanic doesn't work, cross it out and write a new one right there on the card.
The Playtest Paradox
You cannot playtest your game alone. Well, you can, but it's like proofreading your own essay—you'll see what you intended to write, not what's actually there.
Once you have a functional prototype, you need humans. Not just any humans, though. Your mom will tell you it's "nice." Your best friend will tell you it's "cool." You need the "Rule Lawyer" friend—the one who tries to find every loophole to win. They are your greatest asset.
Watching, not teaching
When you sit people down to test your design a home game project, shut up.
Seriously. Give them the components and a rough sheet of rules, then sit in the corner with a notebook. Don't explain the rules. If they play it wrong, don't correct them. That "mistake" is actually a data point. It tells you that your rules are unclear or that their "wrong" way of playing might actually be more intuitive and fun than your "right" way.
Mechanics to Steal (Legally)
You don't need to reinvent the wheel. Almost every modern board game stands on the shoulders of giants. You can't copyright a game mechanic—only the specific artwork and text.
- Worker Placement: Think Agricola or Lords of Waterdeep. You have a limited number of "people" to put on spots to get stuff.
- Deck Building: Like Dominion. You start with a weak deck and buy better cards as you go.
- Drafting: Like 7 Wonders or Sushi Go!. Pick a card, pass the hand.
When you design a home game, try mashing two of these together. What if you had a deck-builder where you also had to move a physical piece on a board? Suddenly, you have a game. This is how Clank! became a massive hit. It took two familiar concepts and welded them together.
The Mathematics of Fun
You don't need to be a calculus whiz, but you do need to understand probability. If you're using two six-sided dice (2d6), you need to know that a 7 is much more likely than a 2 or a 12.
- 7: 16.6% chance
- 2 or 12: 2.7% chance
If your game requires players to roll a 12 to do something cool, they are going to spend most of the night failing. That's not fun. It's frustrating. Balancing a game is often just a matter of adjusting these numbers. If a certain card is "overpowered," make it cost more. If no one ever uses the "Shield" action, give it a secondary benefit, like drawing a card.
Digital Tools for the Home Designer
While paper is king for the first week, you’ll eventually want to move to digital. You don't need Photoshop.
- Tabletop Simulator (TTS): This is a godsend. It’s a physics engine on Steam where you can upload your images and play with friends online. It’s the industry standard for playtesting before manufacturing.
- nandeck: A bit technical, but it’s a free tool that lets you use a spreadsheet to automatically generate hundreds of cards.
- Game Crafter: When you’re ready for a "real" copy, they do print-on-demand for single board games. It’s pricey for one unit, but it makes your design a home game project feel like a real product.
Themes: Why "Zombies" is Usually a Bad Idea
Unless you have a truly unique spin, avoid overused themes like generic zombies, Cthulhu, or "trading in the Mediterranean."
The theme should serve the mechanics. If your game is about high-speed racing, the rules should feel fast. If it's a horror game, the mechanics should make the players feel powerless or trapped. A great example is Wingspan. Elizabeth Hargrave took a theme people thought was "boring"—bird watching—and turned it into a global phenomenon because the mechanics felt perfectly aligned with the hobby.
The Ending is the Beginning
Finishing the game is the hardest part. You’ll get it to 90% completion, and then you’ll want to start a new project. Don't.
The last 10% is where the balance happens. It’s where you realize that the game is five minutes too long, or that the "Blue" player always wins. Keep tweaking. Design a home game that you actually want to play on your own Friday nights. If you find yourself wanting to play your prototype instead of your copy of Catan, you’ve won.
Actionable Next Steps
- The 24-Hour Prototype: Grab a Sharpie and 20 index cards right now. Write one action on each card. Grab two tokens (coins, bottle caps). Create a "win condition" (e.g., first to 10 points). Play it against yourself tonight.
- The Mechanic Mashup: Write down three games you love. Pick one mechanic from each (e.g., "Rolling Dice" from Monopoly and "Area Control" from Risk). Force yourself to sketch a map that uses both in a way that isn't just Monopoly with armies.
- The "Silent" Playtest: Once your cards are readable, give them to someone without saying a word. Watch where they stumble. Take notes on where they look confused. Those points of confusion are exactly what you need to redesign tomorrow.
- Component Scavenging: Don't buy new stuff yet. Raid old, broken games for dice, meeples, and boards. Use the back of a Scrabble board as your new canvas. Low stakes lead to high creativity.
