Original Mechanics

Building a slot game that uses the same mechanic principles as Gates of Olympus — scatter pays on a cluster grid, tumble cascade, multiplier orbs, Ante Bet, free spins — is legal because game mechanics are not protected by copyright (only specific expressions of them are). What is protected is Pragmatic Play's specific artwork, symbol designs, the "Gates of Olympus" name, Greek deity character designs, and proprietary code. An original game built with entirely new artwork, original theme and brand name, and independently written engine code using the same mechanic concepts is legally independent. Algosoft builds every element from scratch — no Pragmatic Play assets are used, copied, or referenced in the delivered game.

The tumble (also called avalanche or cascade) mechanic causes winning symbols to be removed from the grid after a win, with new symbols falling from above to fill empty positions. The refilled grid is then re-evaluated for new winning clusters — if new wins are detected, those symbols are removed and the process repeats. This cascade chain continues until a refilled grid produces no new winning cluster, at which point the spin sequence concludes. Engineered server-side, each tumble step involves: cluster detection on the current grid state, win amount calculation with current multiplier applied, symbol removal, position-by-position new symbol generation from the PRNG, gravity cascade fill of empty positions, and re-evaluation. All state is maintained server-side with the final outcome determined before any animation plays client-side.

Multiplier orbs (symbols with values like ×2, ×3, ×5, ×10, ×50, ×100) land on the grid according to their configured landing weight in the PRNG output. When a winning cascade sequence occurs, any multiplier orbs that land during a tumble step within that sequence are collected. At the conclusion of the spin sequence, all collected multiplier orb values are summed — for example, ×3 + ×5 + ×10 = ×18 — and this sum is applied to the total win generated by all winning clusters in the sequence. Crucially, the orb values are summed (added together), not multiplied together — which gives the system a controlled maximum multiplier ceiling while still creating dramatic high-multiplier moments. The accumulated total carries into free spins when triggered.

The Ante Bet feature allows players to pay a 25% premium on their base bet in exchange for a doubled probability of triggering the free spins bonus on each spin (achieved by doubling the scatter symbol's weighting in the PRNG output). The feature does not change the base game RTP or the average win per triggering spin — it only increases the frequency at which players enter the free spins bonus. Because the free spins bonus is where the highest win potential is concentrated, players who want to encounter the bonus more frequently can use Ante Bet to trade a higher bet cost for a shorter expected time-to-bonus. The RTP impact of Ante Bet must be fully documented for RNG certification lab review.

When free spins are triggered, the multiplier total accumulated during the triggering base game cascade sequence is carried over into the free spins round as the starting multiplier state — it does not reset to zero. This is significant because triggering free spins via a long cascade chain with multiple multiplier orbs may enter the bonus with an already elevated multiplier (e.g., ×15 carried over), dramatically increasing the potential win from the first free spin. The multiplier then continues to accumulate during the free spins round without resetting between spins. Server-side, the multiplier total is stored as persistent session state associated with the player's current bonus round, surviving any brief disconnection or reconnection during the bonus.

Yes — for regulated real-money gambling market deployment, RNG certification from an accredited testing laboratory (iTech Labs, GLI, BMM, or eCOGRA) is required. The certification scope for a scatter-pay cluster engine is broader than for a standard payline slot because the cluster detection algorithm, cascade chain logic, multiplier orb landing system, Ante Bet scatter weighting change, and persistent free spins multiplier state must all be reviewed and verified by the lab. Algosoft builds the engine with certification in mind from the architecture phase and prepares the full mathematical model, algorithm documentation, and RTP audit log infrastructure required for first-submission approval.

Slot template reskins use an existing certified engine with different artwork applied — they cannot implement mechanics like a custom multiplier orb summing system, Ante Bet scatter weight doubling, or persistent free spins multiplier carry-over, because the underlying engine is fixed and not configurable to those mechanics. Algosoft builds a purpose-built scatter-pay cluster engine specifically designed for this mechanic set — every component (cluster detection, cascade state, multiplier accumulation, Ante Bet implementation, persistent free spins state) is engineered from scratch and is fully configurable for RTP, volatility, and mechanic variant tuning. The result is a legally independent, certifiable, owned IP slot game — not a licensed skin of someone else's technology.

A basic scatter-pay slot MVP (cluster engine, tumble mechanic, multiplier orbs, free spins with carry-over, web interface only, no Ante Bet) can be delivered in approximately 10–14 weeks. A mid-level build with full mechanic set (including Ante Bet), iOS and Android native apps, operator dashboard, and compliance panel takes approximately 5–8 months. An advanced build with full custom art production, multiple jurisdiction RTP variants, bonus buy feature, and RNG certification documentation takes 8–12 months. Note that RNG certification by the testing lab adds a parallel 6–12 week review period after submission — this should be planned as an overlap with the final QA and go-live preparation phase to minimise total time-to-market.
