Vialux
Pour colored potions between flasks until every flask holds a single color. There are no ads in the game at all.
Free to play, no ads. There is an optional Premium monthly subscription on iPhone, iPad and Android.
What's inside
- Every level is an order from a customer of the shop. Fill it and a new recipe appears in the Recipe Book. The first version has 60 recipes, which is 300 levels.
- A flask holds up to four layers. You pour the top layer into an empty flask or onto the same color. The first three levels are the tutorial.
- You cannot lose. When there are no moves left, the game offers to undo a move, add a flask or restart the level. Restart is always free.
- Hints, extra flasks and undos can be earned by playing: every level pays out silver. Three undos per level are free.
- Order of the Day: one level, the same for everyone, no helpers. You can send the result to a friend as a picture and compare the number of moves.
- A seven-day reward calendar. If you skip a day, the calendar does not reset. A freeze protects your streak.
Premium
Premium is a monthly subscription that renews automatically. It is on iPhone, iPad and Android. It does not unlock the game: every level can be finished without it. It removes limits on helpers and adds extra looks.
What it includes:
- unlimited undo and hints;
- one extra flask on every level, free;
- the Moonlit Shop theme: a new background, flasks and a star effect;
- double silver from the reward calendar;
- two streak freezes a week instead of one;
- the full statistics history instead of the last seven days, and a Premium badge in your profile.
The Premium price goes down in steps over time since installation, the same for everyone. In Russia it is 299 RUB per month in the first three days, 149 RUB per month from day four, 89 RUB per month from day seven. Only the previous step is crossed out on the card. In other countries the store sets and shows the price in the local currency. The Premium card without a timer is always available in the shop and in the game settings.
If you buy in those first three days, you get the Founder badge and golden flasks with engraving.
In-game currency and hint sets. These are optional purchases: you can earn the currency by playing, and buying it only saves time. There are no ads in the first release. Future versions may have optional rewarded videos: whether to watch is your choice, and we do not show ads to children.
Difficulty does not depend on purchases. The game builds levels the same way whether or not you have bought anything, have currency or have an offer open. If you are struggling, it can only make things easier, never harder.
Limited-time offers. The game may show a starter or themed bundle, a paid "Rescue" after a failed attempt, or a bonus on a currency pack. Every such offer shows its end date and time ("Offer until 24.10, 18:40"), which is set once at the first showing and never restarts. We do not use "last chance" or "today only". More in the privacy policy.
If you have not bought anything for a long time, the game may offer more of it for the same price. The bonus is labeled "A bonus for you, until <date and time>", never goes above a fixed ceiling, and currency bought with the bonus stays with you for good. Next to the offer there is a "Why am I seeing this" link, and in Settings, on the first level, a "Stop showing offers" option.
If you are under 18 or have not answered the age question, the game has no timers, no growing bonuses and no paid "Rescue". Premium in steps and the regular shop remain.
Questions and answers
Does the game have ads?
Not in the first release. No video ads, no banners, no advertising SDKs and no advertising identifier. Future versions may add optional rewarded videos: whether to watch is your choice. We do not show ads to children. If videos appear, we will update the policy and the description.
What does Premium give, and do I have to buy it?
You do not. Every level can be finished without a purchase and without helpers. Premium removes the limits on undo and hints, adds the Moonlit Shop theme, doubles calendar rewards and opens the full statistics. Apart from the theme, you can earn all of that by playing, only slower.
Why am I seeing this offer, and how do I turn offers off?
The game decides which offers to show and when, on your device, using the days since installation, your progress, your purchases and how you reacted to earlier offers. This information stays on the device and is not sent to us. Every offer has a "Why am I seeing this" link with a short explanation. You can turn offers off in Settings: "Stop showing offers" (there is a small link on the offer card too). The Premium card without a timer stays in the shop.
Is the timer on an offer real?
Yes. The end is shown as a date and time, for example "Offer until 24.10, 18:40". It is set once at the first showing and does not restart if you close and reopen the game. After it ends the offer disappears, and the shop price stays at its regular level.
Why do I sometimes get more in-game currency for the same money?
If you have not bought anything for a long time, the game may offer a pack with a bonus: "A bonus for you, until <date and time>". The price does not change, the amount of currency does. The bonus grows in steps up to a ceiling and resets after any purchase. So two players paying the same amount can end up with different amounts of currency, and we show this plainly on the offer screen.
Does difficulty depend on purchases?
No. Levels are built the same way regardless of purchases, wallet or offers. A line like "2 moves short" appears only when that is what actually happened.
What changes for players under 18?
The consent screen has two equal buttons: "14–17" and "18 and over". If you choose "14–17" or do not answer, the game shows no timers, no growing bonuses and no paid "Rescue". Premium in steps and the regular shop remain, with no urgency. Your answer stays on the device.
Is the Shadow League made of real players?
No. The screen is called "Shadow League (recorded results)", and these are recorded results, not live players. They are matched to your progress and named "Shadow 1", "Shadow 2" and so on. The summary reads: "You beat 12 of 29 recorded results". There are no paid league boosters. If you connected Game Center (iPhone) or Google Play Games (Android) yourself, their board with real players sits on a separate tab and is never mixed with the shadows.
What is sent to Game Center and Google Play Games?
Only if you connected them yourself: the game sends them your weekly result (the score and the board), and Apple or Google show it on their board under your profile in that service, by their rules. We do not receive or store your name, profile or friend list from those services. Without a connection the game works the same.
What can I buy, and is Android different from iPhone?
Premium is a monthly subscription that renews automatically, on iPhone, iPad and Android: in Russia 299 RUB per month in the first three days, 149 RUB from day four, 89 RUB from day seven; in other countries the store shows the price in your local currency. You can cancel in your App Store or Google Play settings at least 24 hours before the renewal; after that Premium works until the end of the paid month. The game also sells packs of in-game currency and hint sets. You can play without buying anything.
Does it work offline?
Yes. Levels, the Order of the Day and the calendar run on your device. You need the internet to make a purchase and to send game statistics to our server.
What data do you collect?
A random installation ID and game events: which levels you finished, how many moves, which helpers you used. If you turned on usage statistics, events about in-game currency, quests, offers and purchases are added (what was shown, what was bought, at what price), along with the age group you chose: "14–17" or "18 and over". We also record the fact of a purchase, but we do not have your card details. There is no account, no name, email, phone number, location or contacts. Nothing is passed on for advertising. Details are in the privacy policy.
How do I delete my data?
In the game: Settings → My data → "Delete my data". The game deletes your events on our server and resets the installation ID. If you are offline, it tries again on the next launch. You can also email hello@demda.pro with the subject "Data deletion — Vialux" and paste your installation ID; you can copy it on the My data screen. If you delete the game from your device, local progress is gone.
What age is it for?
There is no violence and nothing scary or adult in the game. It is made for adults: it is not directed at children, and we do not knowingly collect data from users under 14 in Russia or under 13 in other countries. On the consent screen we ask for an age group: "14–17" or "18 and over". If you are under 18 or did not answer, the game has no timers, no growing bonuses and no paid "Rescue".
How do I report a bug?
Email hello@demda.pro with the subject "Vialux". Tell us your device model, system version, game version (it is on the game's store page) and what happened. A screenshot helps.
I paid more for Premium than it costs now. Do I get the difference back?
No, we do not refund the difference: the price of every step is shown before you subscribe. People who subscribe in the first three days get the Founder badge.
Can I buy with a Russian App Store or Google Play account?
In the App Store, Apple currently does not accept payments in Russia, so Premium, currency packs and hint sets cannot be bought with such an account. On Google Play it depends on your country and the payment method on your account: the store processes the payment, not us. The game itself works fully.
