How to play

The game is best played in teams. Players standing across the game on opposite sides are working together. You tilt the board to sink the ball into the correct hole for your team. The holes for each team depend on the game variant you are playing. See our how to play page for more a detailed explanation.

Frequently asked questions

~Is it hard to play?

The rules are very simple, but the challenge of the game is entirely dependent on the ability of your opponents. Experienced players will able to work together with their teammate, conserve their strength, and predict the moves of their opponents. Games between experienced players can be very challenging.

~Can this be played with 2 or 3 players?

No. The function and fun of the game are the forces at each corner handle being created by opposing players. This kind of direct player interaction with the game board is not possible with lower player counts.

~Can this be played with players of varying levels of size and strength?

Yes! Players with better dexterity, fitness, and teamwork can overcome significant disadvantages in strength. Still, it is recommended to try and balance the overall strength between the teams.

~Is this game okay for children?

Yes! Kids love it and have no problem playing. However, it is not recommended that children and adults play together, due to the large physical differences.

~What if I lose the ball?

Replacement balls can be provided. Please send us a message through the contact form.

~Can I get more glow inserts?

Yes, send us a message through the contact form.

Just a blast!

We are a family of 8 with our kids ranging in ages 2-16, so it's not always easy finding a game we can play together. SINKO fits the bill!! We've had a blast with this game and love the different variations!

WOW!! :)

This game is a breath of fresh air ~ literally!
So good to be outside, using some physical exertion and having either some competitive fun or team building fun ~ your choice!
I would highly recommend this to anyone looking for something different to challenge skills and stamina. Great for BBQ's, camping, park days, etc.
Can also be used indoors ~ just give the kiddos some elbow room :)
I purchased this a week ago and have already used it several times with different groups, as well as purchased one for a gift.
The next time one of your children or grandchildren ask for yet another video game (which, by the way, could easily be the same cost) give them a Sinko instead, then sit back and watch the smiles! :)

Big Time fun!

We love sinko! Bringa #bigtime fun to any gathering!
