The Roobet Games category contains exactly 12 titles:
- Crash
- Blackjack
- Limbo
- Dice
- Mission Uncrossable
- Keno
- Mines
- Plinko
- Roulette
- Slide

- Coinflip
Roobet describes its Originals as RNG-based and provably fair. The category links to a separate Fair section, and most Original cards carry a Provably Fair badge. The site does not publish one common RTP for the whole set. Rules, edge, limits and maximum profit must be checked per title.
Published Original limits
Roobet's own Originals guide publishes numeric limits for nine titles. It does not give the same limit block for Blackjack, Limbo or Slide.

Original mechanics
Crash uses a rising multiplier that ends when the rocket crashes. The player must cash out before the crash.
Keno lets the player choose 1 to 10 numbers from a board of 1 to 40. Risk level and the number of picks determine the payout table.
Mission Uncrossable is Roobet's chicken-crossing game. Its published difficulty settings show collision chances of 4% on Easy, 12% on Medium, 20% on Hard and 40% on Daredevil.
Mines supports grids of 25, 36, 49 or 64 tiles. The mine count can be set manually from one mine up to one fewer than the number of tiles.
Dice supports Roll Under, Roll Over, Roll Between, Roll Outside and Roll Between x2 bets on a 0 to 100 range.
Plinko has Low, Medium, High and Lightning modes. Published multiplier ranges are 0.5x to 16x on Low, 0.3x to 110x on Medium and 0.2x to 1,000x on High. Lightning adds path multipliers and dead zones. The board can use 8 to 16 lines, and a fast mode is available.
Roulette uses red, black and green Roobet symbols rather than a standard numbered wheel. The guide lists 2x for red diamond and star, 2x for black diamond and star, 7x for the red and black star, and 14x for the green Roo. Three consecutive green results trigger the Triple Roo Jackpot for qualifying green bettors.
Towers offers Easy, Medium, Hard, Expert and Crazy difficulty levels. The player can cash out after any safe choice.
Coinflip supports 1, 2, 5 or 10 simultaneous games. Players can face another player or a bot that takes the opposite side.
Crash, Keno, Dice, Plinko, Towers and Coinflip are specifically named as titles with a demo mechanism. A wager below $0.01 starts demo play where supported.
Provably fair verification mechanics
Roobet's Fair page provides a separate explanation and an external verification program for every Original. Dice, Mines, Towers, Mission Uncrossable and Limbo use a server seed supplied by Roobet, a player-controlled client seed and a nonce that rises by one after each bet. The player receives the SHA256 hash of the server seed before play. Revealing the seed resets both the server seed and nonce, and the revealed value can be hashed again to check that it matches the earlier commitment.
Plinko adds a game hash for the current board. The board hash changes periodically, while the server seed, client seed and nonce determine the individual result. Keno uses five inputs: a round hash, server seed, client seed, nonce and the numbers selected by the player.
Blackjack uses a server seed, a randomly generated alphanumeric client seed for each game, a game nonce and an actions hash built from the game's actions in chronological order. Its verifier reconstructs the shuffle hash rather than merely displaying a result label.
Coinflip combines the two participants' inputs. Its eight disclosed values are the author, competitor, each player's server seed, each player's client seed and each player's nonce. The client seed is derived from the hash of a future EOS block committed to before that block is mined.
Crash uses a different chain model. Roobet generates two million SHA256-linked server seeds before play and starts with the two-millionth hash, moving backwards through the chain one round at a time. The client seed is a future cryptocurrency block hash selected by commitment before the block is mined. Its public verifier accepts a round's server seed and reconstructs that round plus the previous 100 results.
The Fair page explains reproducibility and pre-commitment, but it does not publish a complete RTP or house-edge table for all 12 Originals. It also does not publish one bonus-contribution rate for the set. The verifier can confirm how a recorded result was generated; it does not prove the advertised RTP over a short session or replace the game-specific rules.
