Which games count as Originals?
Gamdom identifies Crash, Dice, Plinko, Mines, HiLo and Roulette among its in-house products. Check the current game list because operator products can change.

How provably fair verification should be understood
In a provably fair system, information such as hashed seeds can be used to check whether a published round outcome corresponds to the committed random input. That is a check on a specific outcome, not an assurance of favorable results or operator legality in a given jurisdiction.

Mechanics comparison
Crash is time-sensitive because the player chooses when to cash out before an unpredictable crash. Dice settings typically alter win probability and payout. Mines uses a grid with concealed hazards. Plinko uses paths and payout bins. Each needs its own game-specific rules.

How to read theoretical RTP
Theoretical return to player is a mathematical long-run measure, not the amount an individual session will return. Even a high theoretical RTP leaves the possibility of losing an entire entertainment budget.

What a fairness check can and cannot establish
A cryptographic fairness verification can test whether an outcome corresponds to published seeds or hashes under the game's disclosed algorithm. It does not show that a bet has positive expected value, that withdrawals will be approved, or that an operator holds a particular licence. These are separate questions requiring separate evidence.
Gamdom describes a hash-chain system in its Originals help article. Readers should check whether the specific game provides an accessible verifier, seed information and algorithm disclosure. A statement that a game is “provably fair” without a reproducible verification method is not equivalent to performing the verification.
RTP arithmetic without profit promises
Illustrative arithmetic: with a theoretical RTP of 99%, stakes totalling $1,000 have a theoretical aggregate return of $990 under the model, leaving a $10 expected difference. It does not mean that a player placing $1,000 will receive $990; outcomes can be far above or below that figure. The 99% figure is a published generalisation for some Originals and should not be assigned to every game or mode without checking its current rules.
RTP and cryptographic verifiability answer different questions: RTP concerns expected aggregate return over many trials, while verification concerns whether a stated outcome corresponds to the published result-generation procedure.
