PartyCasino does not currently offer a bonus code, so there is nothing to enter when you register or deposit. The offers it does run are shown in the cards above this text, each with its own terms, and the welcome offer, Deposit £10, Get £10 Casino Welcome Bonus, is the one for new players.
That means the useful question is not where to find a code but which of the current offers suits you, if any. The sections below explain how those offers differ from a code, what to check in their terms before you deposit, and who is likely to find them worthwhile. Read the terms shown on the page first. T&Cs apply.
How the current offers differ from a bonus code

A bonus code is a short word or number that you type in to unlock an offer. With no code on offer, the bonuses above are described by the terms listed on each card. The cards show the main conditions, so use them as your starting point rather than relying on a headline.
The welcome offer is the only one of the current offers that is aimed at new players. Its listed conditions are a minimum deposit of £10, wagering of 10x and a validity period of 30 days, and the maximum bonus is £10. Eligible games are listed as selected games. That list matters in practice, because the wagering figure applies to what you play, so check it against the games you actually want. T&Cs apply. The full picture is on the welcome bonus page, and the sign up bonus page looks at the same offer from the registration side.
A wagering requirement is a multiplier. It sets how many times an amount has to be played through before winnings linked to the bonus can be withdrawn. A lower multiplier is easier to meet than a higher one, so it is the figure to compare when you look at two offers. The games that count towards it matter as much as the number: if you like a game that is not on the eligible list, the offer is a poor fit for you.
The same logic explains why the welcome offer is the one to read most closely. It has a stated minimum deposit, a stated wagering figure and a stated validity period, so you can see before you pay in what you would be agreeing to. A headline such as the offer title tells you the size of the bonus, but only the conditions tell you what it takes to use it. Compare the title and the conditions side by side, and give the conditions more weight.
The other two offers are for existing players. Party Prizes (daily free prize wheel) and Mega Party Prizes are covered on the bonuses page. T&Cs apply to both. They are not welcome offers and should not be treated as an alternative way to start an account. For existing players the conditions that matter are the same ones: what is needed to take part, what you have to play through and how long it lasts. Where one of those is missing from an offer, ask the question before you rely on it.
A bonus code, where a casino does use one, is simply a different way of claiming an offer. It does not change the terms attached to that offer. A code that unlocks a bonus with high wagering is still a bonus with high wagering, so the same checks apply whether you reach an offer with a code or without one.

What to check if a bonus code offer appears

Nothing here promises that a code offer will appear. If one does, a few checks save most of the trouble, and they apply equally to the offers above.
Read the full terms before you deposit. The conditions that decide whether an offer is worth taking are the minimum deposit, the wagering requirement, the time limit and the list of eligible games. If any of them is missing from the offer, treat that as a reason to look more closely before you commit.
Check whether a code is needed at all, and where it goes, before you pay in. The deposits page covers how payments work, and it is the place to look before your first payment so that nothing about the process is a surprise.
Look at the maximum bet and the game list as well, if the offer gives them, since these are the rules players most often overlook. Playing a game that does not count, or staking more than an offer allows, is the kind of slip that can cost you the bonus, so check both before you play. Then look at the time limit. The welcome offer, for instance, is valid for 30 days, and that is a condition to plan around rather than a detail to skip.
Finally, keep the offers apart in your mind. Existing-player offers such as Mega Party Prizes are not a second welcome bonus, and the conditions of one offer do not carry over to another. T&Cs apply to every offer.
Is it worth looking for a code?

With no code on offer, there is little to look for. The sensible move is to compare the offers that exist and decide whether any of them suit the way you play.
The welcome offer is the one to weigh up if you are new. Its minimum deposit of £10 is a low bar, and its wagering of 10x is the figure to judge it by. The drawback is that the offer is tied to selected games, so it may not fit if you want to play something else. The validity period of 30 days is also a limit to keep in mind if you do not plan to play regularly.
Think about how you play before you decide. A bonus ties your deposit to wagering conditions, so it suits someone who already plans to play the eligible games and does not mind the time limit. If you play only now and then, or prefer games outside the list, a bonus may add more rules than value. Skipping the bonus and playing with your own deposit is a perfectly reasonable choice, and it keeps the rules simple.
Whatever you choose, a deposit is your own money, so pay in only an amount you can afford to lose. If you are ready to register, the sign up page explains how. Existing players have the two offers named above and can find more on the promo codes page. T&Cs apply.
