Mr Green does not currently offer a sign-up bonus for new players. The offers it does run are shown above, and both are aimed at existing players. The daily offer card shows its minimum deposit and validity period, while the other card gives only the offer's name and the terms to read in full. T&Cs apply.
That changes how you should approach registration. If you are deciding whether to join, treat the account and any promotion as two separate decisions, and do not sign up on the assumption that a welcome reward is waiting. The sign-up page covers how registration works.
The two current offers are the Daily offer (Deposit & stake £10 on Casino in the last 20 days to qualify) and Daily Drops and Wins. Neither is a welcome package, so this page explains how they differ from the sign-up bonus you were looking for and what to check before you rely on either. <<</FIX 1>>>
How the current offers differ from a sign-up bonus

A sign-up bonus is built around joining: you register, make a first payment and receive a reward for doing so. The offers above work differently. They are listed for existing players, so you judge them on what they ask of you as a regular customer, not on what they give you at the start.
The Daily offer (Deposit & stake £10 on Casino in the last 20 days to qualify) is a reload-type offer. Its title spells out the qualifying condition: a deposit and stake on Casino within the period named in the title. The minimum deposit is £10, and the offer is valid for 3 days. T&Cs apply. Before you deposit, read the wagering terms in the full terms, because they determine how much play the offer asks of you.
Daily Drops and Wins is a separate promotion for existing players. It is a different kind of offer from the daily deposit offer, so do not assume the two share conditions. Its details sit in the full terms, and T&Cs apply. The bonus offers page lists everything currently running. <<</FIX 2>>>
What wagering means for an offer like this
A wagering requirement is the number of times an amount has to be staked before winnings linked to a bonus can be withdrawn. A higher multiple means more play before that point, so it is the single most useful figure for comparing offers. When two offers look similar, the one with the lower multiple and the longer time limit asks less of you.
Wagering also interacts with the time limit. The 3 days on the daily offer is how long the offer is valid. Read the full terms to see how that period relates to any wagering before you take part.
Which games count
Bonus terms commonly treat games differently: slots often count in full, while table games and live games may count for less or not at all. This is general advice, not a rule for any particular offer. Check the game contribution section of the terms before you pick what to play.
This matters most if you prefer blackjack, roulette or live tables. A promotion tied to Casino activity may not suit those games in the same way it suits slots. The slots and live casino pages show what is on offer in each area.
How this compares with a welcome offer
A welcome offer is usually judged by its headline reward and its conditions together. The current offers at Mr Green invite a different question: would you be depositing and staking on Casino anyway? If so, the offer is an extra on top of play you have already chosen. If not, an offer should not be the reason to start.
If you came here for details of a new-customer reward, the welcome bonus page is where such offers are covered. Check the terms there against the cards above before drawing any comparison.

What to check before taking any offer

No sign-up bonus is available, so there is no code to enter for one and no sign-up-specific rule to break. The risks sit with the offers that are available, and with the habit of treating any offer as a reason to deposit. These are the points that most often cause trouble.
Misreading the qualifying condition
The title of the Daily offer (Deposit & stake £10 on Casino in the last 20 days to qualify) carries the qualifying condition. A deposit alone is not what the title describes: it names a deposit and a stake on Casino. Read the whole title before you pay in, not just the first few words.
Missing the minimum deposit
The minimum deposit for the daily offer is £10. Check that the amount you intend to pay in meets it before relying on the offer. T&Cs apply. The deposits page explains how to fund your account.
Ignoring the time limit
The daily offer is valid for 3 days. That is the validity period of the offer, so plan around it and check the terms for anything else the period affects. Do not assume it is a wagering deadline unless the terms say so.
Not reading the wagering and game rules
Wagering, game contribution and any maximum stake while an offer is active are the usual places where players lose a bonus. Read those headings in the terms before you deposit, because they set what you actually have to do. Open the terms and conditions and the promotion's own terms and read them through before paying in.
Is it worth it?

If you wanted a sign-up bonus, there is nothing to take at the moment, and the sensible move is to not register for that reason alone. If you are comfortable with Mr Green for its games and how it works, the decision is about the account, not a promotion.
The Daily offer (Deposit & stake £10 on Casino in the last 20 days to qualify) suits an existing player who already deposits and stakes on Casino and would do so regardless. For that person, a minimum deposit of £10 and a validity of 3 days are conditions to fit around existing habits. T&Cs apply.
It is a poor fit for anyone who plays rarely, for a player who would deposit mainly to qualify, and for someone who wants a reward at registration. The short validity period is the main downside to weigh, and the wagering terms in the full terms need reading before you commit. Read the full terms of Daily Drops and Wins too before you join in, as T&Cs apply to it as well.
Whatever you choose, a deposit is your own money. Pay in only an amount you can afford to lose, and use the limits on the safer gambling page if you want them. If a clear sign-up bonus is what you need, wait for one to appear on the bonus offers page and compare its wagering, minimum deposit and time limit against the cards above before deciding. <<</FIX 3>>>
