Thanks yahoo for extending the invitation, here's my review of L0tt0. A tad image-heavy though
HomepageThe first impression is the retro-ish look and how images are pixelated to instil a feeling of nostalgia. I like how simplistic it is without overwhelming the user with too many graphics and promos as seen in other casinos so I don't have to scroll all the way to the bottom especially on mobile devices.
While browsing through the bets, I noticed that the tip user function is present but this would go hand-in-hand with a chat widget, which is not present for now.
One thing that I don't really understand is the lotto system. I see some tickets from bets but no prize pool, and the information icon doesn't direct me to any related article. Work in progress?
Also a little suggestion: As I noticed almost all headers or titles are centered, the "PICK FROM THE CLASSICS" header could align with the "PLAY LOTTO ORIGINALS" or simply shift the latter to the side of the container to follow the former if the "Bets" counter is to remain where it is.
• Simplistic, very responsive, no performance issues when navigating
• However there were times the site fails to load, resulting in an "Unable to connect to the database. Please try again later" error page. Likely a temporary occurrence.
• On devices with small(er) monitors or displays such as my 11" Macbook Air 2015, I'm unable to click on the 'I agree' button below both checkboxes

• From Big Wins section, High-Low entries shows up as Unknown Game but it shows up as Bullseye from the games dropdown. Likely a misname?

• Also the popup from bet or win details should have more spacing for large wins as the font texts often carry over to a new line. Example is betID 8270098 (view the WON amount)
HeaderBlack and yellow color scheme compliment each other very well. The animated jumping avatar beside the username is a cutesy touch; a refreshing take from the standard user-defined static profile images. Responsive on mobile too.
However the balance does not update when opening multiple tabs.
• Site balance positioned in the middle, can't miss it (in a good way)
• Games from the hamburger menu could be sorted in ascending order (e.g. A-Z)
• Mousing over the username button should have a dropdown for easy logout and menu access instead of having to click on it to load the profile page.
User ProfileShows the necessary stats although I feel that there are multiple improvements from here; one of them would be some sort of self-exclusion or balance vault:
• Stats could be more descriptive (e.g. largest multiplier from which gamemode, instead of just stating the largest multiplier)
• Filters would be useful for recent bets/ top 10 profit/ top 10 multi tabs
• Private profile feature under 'Data and Privacy' not working (yet)
• Under 'Wallet and Payments', transactions do not show the dollar/ fiat value

• Affiliate programs should describe the benefits for both referee (if applicable) and referrer
RegistrationRegistering is straightforward and no-fuss. Uses a unique link to login is rare but I like it. Just like how other casinos incorporate SSO (Single Sign On), this reduces the need for another password and is somewhat more secure.
• On the Account Setup step, the popup is scrollable due to the dropdown. Dropdown contents should render outside the popup to remedy this
DepositCrypto selections are somewhat smallish. Would be good to state a minimum deposit (or not) if applicable as many websites do not credit deposits below the threshold, although this is addressed in the FAQ.
Observations on Games1) I like how standardized the layouts of each game are; icons on the left along with the betting counter, game UI and controls towards the middle and right
2) Last placed bet is saved across all games, although the minimum base bet (1 cent) is briefly shown when I switch between games.
3) Since 1 cent is the minimum bet, the amount text field should auto-correct it to 1 since I could enter $0.00 and place a bet (although the system then adjusts it to 1 cent)
4) This doesn't happen with the autobet count however; entering 1 auto-adjusts it to 2
5) Autobet settings work correctly such as bets on wins and losses
6) There is a redundant 'X' button below the autobet option since its already a dropdown button by itself
7) The Game Settings > 'Remember Last Bet' toggle is unable to be disabled in all games
8 ) No performance issue observed in all sessions
9) My previous bets tab entries should correspond to the current games I play. For instance, if I'm on Dice, I want to see my previous dice bets instead of Baccarat.
10) The dark overlay of non-interactable elements while autobetting is nice, but it causes some overlap of the site menu as well when scrolling (more obvious with lottery tickets animated sprite)
Dice• Slightly lower house edge than some other websites (competitor offers 4,800x for a 0.02% win chance, L0tt0 offers 4,848.50x)
• Entering the value in the multiplier field doesn't auto-round or adjust until bet starts. For instance, I enter 50, click away from the text and the value remains at 50. Once I place a bet, it auto-adjusts to 50.24.
• A nice-to-have feature would be a control to increase the speed between rolls as it takes over 1 second per roll.
• The "Dice: Simple Rules, Serious Pay" container contents could be featured separately like the "Game Rules" button to reduce clutter
Roulette• Not able to bet on green/ 00, very high house edge
• Unable to see multiple selected betting combinations (e.g. choosing even + odd)
• Fourth bullet point from 'How to Win' section shares the same line as the third bullet point

• The "Roulette: New Spin On Old Classic" container contents could be featured separately like the "Game Rules" button to reduce clutter
Lucky 7s• The "Lucky 7s: The New Classic 777 Slot" container contents could be featured separately like the "Game Rules" button to reduce clutter
Keno• The "Keno: Fast Pace With Massive Wins" container contents could be featured separately like the "Game Rules" button to reduce clutter
Poker• The "Poker: The Best Crypto Poker Slot" container contents could be featured separately like the "Game Rules" button to reduce clutter
Bullseye• One of my least favorite games with hardly any hits even on the lowest risk level (clearly reflected in the RTP)
• The "Bullseye: The High Variance Slot" container contents could be featured separately like the "Game Rules" button to reduce clutter
Bingo• I don't see how the game randomizes the risk by enabling the function. I still see the same payouts and risk level on each bet.

• The "Bingo: The Ultimate Crypto Bingo" container contents could be featured separately like the "Game Rules" button to reduce clutter
Pick 6• At times when attempting to bet, the webpage throws a "Something went wrong!" error and requires a refresh. This might precede the risk level showing 0 instead of the minimum 1. Hard to point out the root cause but previous interactions involved manually inputting row numbers.

• The "Pick 6: Classic Lotto Meets Crypto" container contents could be featured separately like the "Game Rules" button to reduce clutter
Plinko• Could see some slider for rows adjustments instead of merely adjusting by risk level
• Another game alongside Bullseye to join the least favorite due to the mines (0x) instead of sub-1 multipliers on higher levels
• The "Plinko: It's All About the Bounce" container contents could be featured separately like the "Game Rules" button to reduce clutter
Blackjack• Side Bets counter could be slightly larger since the betting buttons are pretty small
• If I set the minimum bet to 1 cent (instead of the default 2), the game still runs but will show in the history as 0 cents. Not sure why it's 2 cents here unless that's intentional

• The "Blackjack: Classic Play, 99.4% RTP" container contents could be featured separately like the "Game Rules" button to reduce clutter
Coinflip• The left/ right and dice buttons don't indicate their functionalities (should have some tooltip or explained in the game rules)

• The "Coinflip: The Ultimate 50/50 Hit" container contents could be featured separately like the "Game Rules" button to reduce clutter
Baccarat• Side Bets counter could be slightly larger since the betting buttons are pretty small
• Game guide has two scroll bars from two containers

• The "Baccarat: Simple Rules High Stakes" container contents could be featured separately like the "Game Rules" button to reduce clutter
Withdraw• Fees are fairly reasonable for BTC at $0.39 at the time of withdraw
• Fee tooltip is compressed and texts don't wrap properly when mousing over the icon
FooterNothing much to complain here since the layout is clean, but I'm curious about the "v5" which doesn't reflect in the title. Might want to keep it internal or under wraps. I've seen it on some faucet sites but they indicate the version as part of the changelog.
• In the FAQ, it mentions that only BTC, LTC and DOGE are supported without SOL, but deposit has all 4 coins. Possibly an oversight.
Conclusion: I like the simplicity of the website with some twist to the standard games but they result in higher house edges which can be off-putting to some, me included. Roulette and Plinko are good examples. Adding the chat widget would definitely increase player activity with the rain feature (seen in the TOS).
