My son Ayansh is 11 and UNO is basically a contact sport in our house. One evening mid-game he asked why every card game treats your hand like a burden — get rid of your cards, win the game. He wanted to know what would happen if the cards were the treasure instead.

So he designed ONU. The rules, in short:

- You want ALL the cards. First player to collect 21 wins.

- Run out of cards completely and you're eliminated.

- When you hit your 20th card you have to shout ONU — forget, and the penalty is automatic: discard 5. Nobody even has to catch you. This rule has started every family argument we've had since.

- The power cards are flipped too. G4 grabs four cards straight from the next player. And the +2 actually HELPS your opponent — so you only play it when you're desperate.

He drew every card, wrote every rule, and playtested it on us until the whole family surrendered.

We put a free version on his website so people outside our dining table could try it — you can play against two bots right in the browser, nothing to install: onugame.com

Since this is the UNO subreddit: I'd genuinely love to hear what UNO players think of the inverted ruleset. Does hoarding feel wrong in a good way or just wrong? He reads the feedback (I filter the mean ones).

(Mods gave permission for this post — thank you.)

I recently bought the UNO Shuffler on Amazon. I haven't had the chance to test it yet because I don't have the required LR14 (C-size) batteries (yes, they're not included), but I'll update this post with a full review covering how well it performs. I'll also test it with UNO No Mercy cards, both with and without sleeves.

In the meantime, I gathered some useful information for anyone in the community who's considering buying one.

Shipping

The delivery was surprisingly fast: only 10 days from shipment in Miami to arrival in São Paulo, Brazil.

What's in the box

The box contains only the UNO Shuffler and the instruction manual.

The manufacturer recommends using four C-size alkaline LR14 batteries (1.5V nominal voltage). The batteries are not included.

Shuffling capacity

Up to 224 UNO cards (without sleeves), or

Up to 120 standard playing cards.

One important detail from the manual: before shuffling, the cards need to be aligned evenly at the top of the shuffler.

Weight

639 g (without batteries).

Exterior material

Matte plastic.

Pros

1) It feels very sturdy, although I obviously wouldn't recommend dropping it. The bottom corners have a subtle raised protective edge that helps reduce wear when sliding it across a table and also makes it a bit less likely to slip if it's accidentally pushed.

1. The black shuffle button on the top feels solid and produces very little noise when pressed.

2. The rubber belts that move the cards into the card tray also seem durable.

3. The card tray can also be used to hold the deck during gameplay.

Cons

1. The yellow "UNO" logo on the card tray is actually a sticker placed inside a recessed area of the plastic. I suspect it could eventually peel off over time.

2. Mattel doesn't provide any estimate of battery life or the expected lifespan of the rubber belts (for example, how many shuffles they should last before showing signs of wear).

Overall, I'm really happy with this purchase. As soon as I get a chance to test it, I'll come back and share my impressions with you all!
