Inco x Megapot Summer Game Jam: The Winners

Over two weeks this summer, we gave builders a simple challenge: build a fun onchain game.

We organized a series of workshops to give builders some tips and ideas, and Megapot joined as a cohost. The result was the Summer Game Jam.

Projects participating in the Inco track had one simple constraint: their game had to leverage Inco Lightning to unlock new gaming dynamics powered by onchain confidentiality.

Thank you to everyone who participated, there were some great projects. Below are the details of the winners, plus some honorable mentions.

Inco Track Prize Winners

🥇 1st place — Mentalist

A murder mystery where you stake on your read of the room.

Each case hands you a crime scene and a set of suspects. Every suspect tells you where they were and what they were doing, and one of them is lying. That person is the killer.

Once you've decided, you stake USDC on your pick. Your choice is encrypted on your own machine before it ever touches the chain, so no one can see who you backed while the case is open. When the case closes, everyone who guessed wrong pays out to everyone who guessed right, proportional to what they staked. Winners cash out in Megapot jackpot tickets or plain USDC.

It's a clean demonstration of confidential commitments: everyone commits in public, no one can copy anyone else's answer, and the reveal is trustless.

🥈 2nd place — Zunno

Onchain Uno where your hand stays private thanks to Inco Lightning.

Two players, standard Uno rules, played fully onchain on Base. Each hand is kept private through Inco's confidential compute, dealt and played as encrypted state the contract enforces rules against, not parked offchain on a server you have to trust.

A creator opens a table, a second player joins, and the deck is shuffled confidentially onchain and dealt in batches. Each player can only ever decrypt their own cards. On every turn, the contract checks the claimed play against the encrypted hand before applying the rules (color and value matching, Draw Two, Skip, Reverse, Wild, Wild Draw Four). First to empty their hand wins. No dealer, no server-held cards, no way for either player — or the developers — to peek at an opponent's hand or rig the deck.

And every table doubles as a free Megapot entry: startGame buys a lottery ticket, and if it hits the daily drawing, the payout splits equally across everyone who was at the table.

🥉 3rd place — Hextract

A tactical extraction game leveraging Inco Lightning for confidentiality.

Both players seal two simultaneous orders into a single ciphertext. The contract resolves everything — movement, scans, attacks, decoys, picking up the Core, extraction — using encrypted comparisons and math, so the game logic never branches on data anyone can read. Positions, integrity, decoy beacons, the Core's location and custody, scan ranges, and even the provisional winner all stay encrypted, granted only to the wallet entitled to see them.

After each round, a player can decrypt only their own sightline. They never see a rival's full state unless that rival is within two tiles. Fog of war, enforced cryptographically rather than by a referee. When the match ends, the contract verifies the attestation and the exact outcome before publishing a winner or a draw.

Honorable Mentions

These projects pushed the prize winners close, and we wanted to dedicate some space to showcase what they built.

AEGYLAX

A co-op planetary-defense game where the attack, your intel, and your shot all stay encrypted until the moment of impact.

Players join Defense Operations to defend the planet against an incoming strike whose trajectory is encrypted onchain. You deploy Recon Probes to pull noisy, incomplete hints about where it's headed, then commit a single private decision on where to intercept. Your Defense Point stays encrypted until impact; only then does the contract reveal the real trajectory and every submitted point and score who actually landed the hit. Successful defenders split the prize pool, and a round where the planet falls feeds a global jackpot that funds a future free community defense operation.

pi River

Confidential heads-up Texas Hold'em on Base Sepolia.

Sign in with Google, get a silent play wallet (no MetaMask required), and jump into Quick Play against a bot or a friend. Your hole cards are encrypted with Inco Lightning the moment they're dealt, only you can see them. 

There's progression, cosmetics, rewards, and Megapot ticket credits around the table, but the core is confidential poker that's live today.

Glass Bridge Royale

Squid Game's glass bridge, played onchain.

A bridge of N steps, each with two glass panels: one holds your weight, one shatters. The map is drawn inside a secure enclave and stored on Base as a single encrypted word that no one can read. Players stake tokens and cross one at a time in the order they joined. Those that survive split the pot, weighted by how many panels they opened themselves, so going first is dangerous but pays far more than hanging back.

Thanks for Playing

Thank you to everyone who participated, whether you built a hackathon projects or just tuned into the livestreams. We had fun and hope you did too. And we hope that you come away with an idea of the power confidentiality brings to the onchain gaming space.
