# BitKong > BitKong is the brand behind Tower — the original provably-fair Bitcoin climbing game, launched in 2015. In Tower, players climb a grid one step at a time, avoiding hidden poop tiles (step on one and you slip off the tower) and deciding when to cash out. The original 2015 product was the character-driven Bitcoin game in a market full of chrome-and-neon seriousness. The relaunch keeps the DNA: provably fair gameplay (three-party entropy: server seed + operator seed + player seed), the ape, the jungle, and a worldview where climbing is sacred, losing is funny, and winning is suspicious. BitKong is a game and brand licensor, not a casino or operator — licensed gaming operators integrate Tower on their own platforms. Tower is playable as a free demo on bitkong.com. ## Story - [The Story of Kong](https://bitkong.com/story.md): The mythic tale of how a player finds the tower, meets Kong, hears about Old Mara, climbs, and learns the only question that matters in the jungle. ## Learn - [The Climb](https://bitkong.com/learn/the-climb.md): How Tower works, top to bottom. The grid, the slips, the cash-out, and the five difficulties from Easy through Nightmare. - [The Three Seeds](https://bitkong.com/learn/the-three-seeds.md): How provably fair actually works. Server seed, operator seed, client seed, the nonce, the HMAC-SHA-256, and how to audit any game yourself. - [When to Stop](https://bitkong.com/learn/when-to-stop.md): How the climb math punishes greed, in numbers. Survival rates that compound brutally fast, the gambler's fallacy, the win-cap nobody honors but should, and bankroll restraint without the lecture. ## Core pages - [Home](https://bitkong.com/): Landing page.

BitKong is not a casino, not an operator, and not a payment processor. - Operator model: licensed gaming operators integrate Tower on their own platforms. The operator holds the gambling licence, handles KYC/AML, wallet custody, deposits, withdrawals, bets, payouts, disputes, customer support, and tax reporting. The operator is the sole counterparty to the player. - Liquidity providers (where applicable): some operator platforms use third-party liquidity providers to back the bet pool financial exposure. Neither BitKong nor the liquidity provider is a counterparty to the player; the operator is. - Provably fair: every Tower outcome is generated using three-party entropy (server seed + operator seed + player seed), committed via hash before each bet and revealed after. Outcomes are mathematically verifiable; BitKong cannot tamper with results, and neither can the operator after commitment. - Heritage: launched in 2015 as the original character-driven provably-fair Bitcoin game. The ape, the jungle, the poop tiles — all distinctive from day one. - Tower mechanic: climb floors one step at a time, avoid the hidden poop tiles (step on one and you slip off the tower), decide when to cash out. The longer you climb, the more you risk and the more you can win. - Difficulty levels: Easy, Medium, Hard, Expert, Nightmare. Each difficulty changes the poop-tile density and the reward curve. - House edge: low single digits, historically around 3%, varying by difficulty and row depth. Disclosed openly. - Kong: the in-game character. An ancient ape with a personality, moods, and memory of every climber. Not a mascot — the voice of the brand. Kong calls the hazard tiles "slips." - Tribes: Kong assigns every climber to one of four tribes — The Patient, The Reckless, The Watchers, The Strange. - Old Mara: the legendary climber who reached floor 47 once and disappeared. Floor 47 is "the Mara Line" — the unmatched record. - Currency: Kong refers to BTC as "bananas," sats as "seeds," and stablecoins as "paper bananas." - Demo: the Tower demo on bitkong.com runs with no real money, no accounts, and no deposits. Real-money play happens on partner operator platforms.
