32Red currently lists three offers: Play £30 Get 320 Free Spins for new players, and My Red Rewards and Red Ruby Rewards for existing players. The cards above show the key terms for each, so check them before you deposit. T&Cs apply.
How the offers work

Play £30 Get 320 Free Spins is the offer for new players. It comes with 320 spins, and the eligible game is Big Bass Splash. It needs a minimum deposit of £30, it is valid for 30 days, and the wagering is 10x wagering on Free Spins winnings. T&Cs apply.
The wagering applies to winnings from the spins, not to the deposit. The eligible game matters too: the spins are tied to Big Bass Splash, so the offer suits someone who is happy to play that game. If you would rather choose your own game, the offer gives you less room. The welcome bonus page goes through this offer step by step.
My Red Rewards and Red Ruby Rewards are for existing players, not for new accounts, so do not treat them as welcome offers. Read the terms for each before you rely on it. T&Cs apply. The VIP programme page covers the second one.
The three offers also differ in who they are for and how much you can see before you commit. The welcome offer has its wagering, minimum deposit and time limit set out on its card, so you can compare it against your own plans in advance. My Red Rewards and Red Ruby Rewards reward players who already have an account, and they sit alongside the welcome offer rather than replacing it. See their cards above for the key terms. T&Cs apply.

What can cost you an offer

Most lost bonuses come from skipping the terms. For the welcome offer, check the time limit of 30 days, the minimum deposit of £30 and the eligible game, Big Bass Splash, before you pay in. Do not assume that an offer for existing players follows the same rules as the welcome offer. Their terms can differ, so read the terms for the specific offer in front of you. The full rules are in the 32Red terms, and the terms and conditions page on this site is a good place to start. T&Cs apply.
Another common slip is accepting an offer without reading which game it applies to. For the welcome offer that game is Big Bass Splash, so check that it is a game you want to play before you deposit. The same goes for the wagering, which is 10x wagering on Free Spins winnings: know what it covers before you start playing. T&Cs apply.
Keep the details of what you accepted. If a question comes up later, you will want to know which offer you took and when.
Keep in mind that an offer is a set of conditions attached to your play, and the offers listed here are the ones the cards above show. Their terms are what count, so compare the cards rather than relying on the names alone. T&Cs apply.
Is it worth taking?

The welcome offer suits a new player who already planned to deposit at least £30, who is comfortable with Big Bass Splash as the eligible game and who is fine with 10x wagering on Free Spins winnings. It is less suitable if you want to pick your own games or want a deposit that is lower than the minimum.
The honest downside is that every bonus ties your play to conditions. The wagering requirement and the 30-day limit mean you have to keep track of what the offer asks of you. The welcome offer also asks for a deposit of at least £30, so it is worth deciding whether that amount fits your plans before you create an account. Declining an offer is a fair choice if the conditions do not fit how you like to play.
If you are a current player, the other two offers are the ones that apply to you, and the welcome offer is not available as a second welcome. Check your account and the cards above to see which is relevant. T&Cs apply.
Any deposit is your own money, so pay in only an amount you can afford to lose. When you are ready, the sign up page covers creating an account and the deposits page covers paying in. T&Cs apply.
