Hedera Coinflip
Hedera Coinflip is a decentralized application (dApp) built on the Hedera network that offers a simple, "double or nothing" style betting game. Users can wager HBAR for a 50/50 chance to double their bet. The platform's core value proposition lies in its commitment to transparency and fairness, which is achieved through its unique use of the Hedera Consensus Service (HCS).
The fairness of each flip is guaranteed by a provably fair mechanism that prevents manipulation by either the player or the platform operator. When a user initiates a flip, a combination of a server-provided seed and a client-provided seed is submitted to the Hedera network via HCS. The immutable and unpredictable consensus timestamp assigned to this transaction by the decentralized network is then used to determine the outcome. Because this timestamp cannot be influenced or known in advance, the result of the coin flip is truly random and publicly verifiable.
A small percentage of each wager contributes to a progressive jackpot, which can be won by players who achieve a specific, consecutive number of wins. This jackpot serves as the platform's primary revenue model while also creating an exciting, high-reward target for dedicated players.

HGraph Punks is a non-fungible token (NFT) project built on the Hedera network under developer Turtle Moon. It has been active in the HBAR NFT space since 2021. The project draws thematic inspiration from the widely recognized pixelated "Punks" style of profile picture (PFP) collectibles.
A significant feature of HGraph Punks is its point system that utilizes the Hedera Consensus Service (HCS). This system enables mainnet-auditable leaderboards, with points directly linked to the NFTs. This allows holders to earn, track, and engage in a competitive and transparent manner. The project also supports NFT staking, where users can stake their HGraph Punks to accumulate points.
HGraph Punks and its parent entity, Turtle Moon, actively contribute to the Hedera ecosystem through community endeavors and the development of open-source Hedera Consensus Service (HCS) tools. Additionally, HGraph Punks has collaborated on community-focused initiatives such as "Liftoff," presented as a virtual music venue and social environment within the Hedera ecosystem.

Slime World is a play-to-earn (P2E) mobile game developed by NADA Digital. It’s the flagship title published under Hedera Guild Games and is available on Android and iOS. The game leverages the Hedera blockchain platform's speed, low transaction fees, and carbon-negative footprint to offer an engaging blockchain gaming experience where players collect and nurture pets called "Slimes" to protect their world and defend against the encroaching "Dark Slimes."
Players complete quests and embark on adventures to earn in-game currency called "Orichalcon" through various activities. The Orichalon can be exchanged for the Hedera Guild Games (HGG) token (formerly NADA Protocol token) a utility token based on the Hedera blockchain. It can be used within the game for upgrading player’s Slimes, purchasing items to aid in adventures, and creating unique Slime NFTs that can be collected and traded via an in-game marketplace.
Gameplay centers around a strategic tower defense-style "infinite mode" where players take on waves of enemies and a "PVP arena mode" wherein players battle one another using their owned or rented Slime NFTs.
Slime World also features mini-games such as "Super Jump" and "Road Crossing," a roulette system for rewards, enhanced social features including user profiles and global chat, and a built-in multi-staking service for HGG tokens.
