Alchymedes is a Yggdrasil Gaming video slot released on 24 January 2017. Alchymedes uses a 5x4 reel layout with 60 fixed paylines, level progression, spreading Wild patterns and a multiplier that can reach 100x. Alchymedes replaces a conventional free-spins round with a system in which winning positions are marked until all 20 places on the reels have contributed to a line win.
Alchymedes places its reels inside an alchemist’s laboratory, with potion vessels showing the current Wild pattern and multiplier state. Alchymedes pays qualifying combinations from either outer reel across 30 lines in each direction. Alchymedes requires at least three matching symbols on adjacent reels for a standard line win.
Alchymedes carries progress from spin to spin within the selected coin denomination. Alchymedes turns positions gold when they form part of a winning payline, and the level ends after every position has been marked. Alchymedes then presents a choice that affects the feature potential of the following level.
Alchymedes is listed by Wildz with 96.10% RTP, a platform volatility score of 2.5/10 and demo play enabled. Alchymedes configurations can vary between operators, so the information panel in the loaded game remains the relevant source for the active rules and staking options. Alchymedes does not use a progressive jackpot.
Alchymedes evaluates 60 fixed paylines after each paid spin, split evenly between left-to-right and right-to-left wins. Alchymedes forms ordinary payouts when at least three matching symbols connect on consecutive reels from an outer reel. Alchymedes can therefore produce qualifying combinations from either side of the grid.
Alchymedes also records which of the 20 positions have appeared in line wins during the current level. Alchymedes keeps those positions marked until the remaining spaces have also contributed, at which point the level-completion sequence begins. Alchymedes outcomes remain random, and previous marked positions do not guarantee when the final space will be completed.
Alchymedes uses level completion as the main route into its feature choices. Alchymedes colours each winning position gold and retains that mark through later spins at the same selected denomination. Alchymedes completes the level only when all 20 reel positions have been covered by winning paylines.
Alchymedes stores a separate progression state for each available coin denomination. Alchymedes may therefore show different level progress after the stake setting changes. Alchymedes does not let the player select which symbols or positions will form the next result, so level completion cannot be forced by a betting pattern.
Alchymedes assigns a Wild pattern at the start of each level and displays it beside the reels. Alchymedes contains more than 15,000 possible patterns, and a landed Wild spreads to the positions shown by the active design. Alchymedes retains that pattern until the current level has been completed.
Alchymedes can place part of a displayed pattern beyond the edge of the 5x4 grid, in which case those outside positions do not create extra Wilds. Alchymedes uses the expanded Wilds as substitutes when evaluating the resulting paylines. Alchymedes does not allow the displayed pattern or the landing point of the initiating Wild to be chosen in advance.
Alchymedes begins each level with a 1x Level Completion Multiplier. Alchymedes can raise that value randomly by between 1x and 5x on a spin, with a confirmed feature ceiling of 100x. Alchymedes applies the accumulated multiplier only to the winning combination that completes the level.
Alchymedes does not multiply every payout made while the level is in progress. Alchymedes resets the feature structure when the next level starts, subject to any awarded starting-multiplier feature. Alchymedes multiplier growth is controlled by the game and cannot be made certain by increasing the stake or waiting for a particular symbol.
Alchymedes shows the Alchemist’s Scales after a completed level and asks for a choice between a Wild potion and a Multiplier potion. Alchymedes uses the green Wild choice to improve Wild-pattern potential, while the red Multiplier choice improves multiplier potential for the following level. Alchymedes makes this decision part of the progression system rather than a separate wager.
Alchymedes can then award one of 6 random features: 100-2,000 coins, a 2x starter, a 3x starter, 1 extra pattern position, 2 extra pattern positions, or Rapid Multiplier Growth. Alchymedes uses Rapid Multiplier Growth to increase the level multiplier on every spin during that level. Alchymedes does not guarantee that a random award will appear after any particular completion or that a chosen potion will produce a specific result.
Alchymedes has a Wildz-listed return to player of 96.10% for the MGA build used by this page. Alchymedes RTP is a theoretical long-run percentage calculated across a very large number of game rounds. Alchymedes can return more or less than that figure during any individual session.
Alchymedes RTP does not describe the chance of winning on the next spin or the time needed to complete a level. Alchymedes results remain random even when many positions have already been marked. Alchymedes players should check the in-game information panel because a different operator or market configuration may use different settings.
Alchymedes is rated 2.5 out of 10 on the platform volatility scale, placing it in the low-volatility band used by Wildz. Alchymedes can still produce losing spins and uneven sequences despite that classification. Alchymedes feature progress changes the presentation of play but does not remove financial risk.
Alchymedes volatility describes the modelled distribution of results rather than a promise of frequent returns. Alchymedes can complete one level quickly and require many more spins for another. Alchymedes does not become due for a payout after a dry sequence, and stake size does not change that principle.
Alchymedes has a confirmed maximum Level Completion Multiplier of 100x. Alchymedes applies that multiplier only to the line win that marks the final required position in a level. Alchymedes should not have the 100x feature ceiling described as the total maximum win, because those are different measurements.
Alchymedes does not have a verified overall maximum-win multiple in the platform data used for this page. Alchymedes players should consult the active paytable for any operator-specific payout cap or maximum-exposure rule. Alchymedes outcomes remain subject to the game rules, and the presence of a high multiplier does not guarantee a high-value completing win.
Alchymedes starts after the player selects an available stake and presses spin. Alchymedes then evaluates both directions of its 60 paylines, marks any newly covered positions and applies the active Wild pattern. Alchymedes should be played only after the paytable, level state and current multiplier have been checked.
Alchymedes real-money play through a Great Britain-licensed operator is subject to statutory online-slot limits. Alchymedes has a maximum stake of £2 per game cycle for ages 18-24 and £5 for ages 25 and over at such operators. Alchymedes stake controls set the financial amount at risk but do not improve the probability of a winning result.
Yes, Alchymedes can be played on compatible mobile phones and tablets as well as desktop devices. Alchymedes preserves the 5x4 grid, level markers, potion choice and multiplier display in its mobile presentation. Alchymedes access depends on a supported browser, device and operator connection.
Alchymedes mobile play uses the same random game logic as the desktop version when the same configuration is loaded. Alchymedes does not become more likely to complete a level because the screen or input method changes. Alchymedes players should keep the progress indicators visible before confirming another paid spin.
Yes, Alchymedes has demo play enabled in the Wildz game configuration. Alchymedes free play uses virtual credits to demonstrate the paylines, level system, spreading Wilds and multiplier behaviour. Alchymedes demo winnings cannot be withdrawn or converted into a real-money balance.
Alchymedes demo results do not predict the sequence produced during later paid play. Alchymedes uses random outcomes in both modes, and completing a level in the demo does not make the same event due with real money. Alchymedes free-play access at a Great Britain-licensed gambling site requires age verification.
Alchymedes may be supplied in Great Britain by an online casino holding the appropriate Gambling Commission permission and carrying the Yggdrasil Gaming title. Alchymedes players must be at least 18 years old, complete the operator’s checks and remain within the online-slot stake limits. Alchymedes rules and RTP should be reviewed in the game panel provided by the operator that supplies the session.
Alchymedes is listed internationally by Wildz, while Wildz states that visitors from the United Kingdom are redirected to partner casinos. Alchymedes players should use the Gambling Commission public register to check the business that ultimately provides the game before depositing. Alchymedes access should not be assumed from an international catalogue listing alone.
