It seems we don't know much about multiples of 3.

Can you win by luck? Can't you win just by luck?
Will even two disappear? Can't get rid of even 10 pieces?

If the sum of the connected numbers of the same mark is a multiple of 3, it's a Sunbyder!

If you erase it once, your opponent will attack.
Let's connect for as long as possible and aim for a chain!
The attack power is doubled by chaining. Let's aim for a big reversal!
If you erase the heart, it will recover.


This is a game inspired by university entrance exam questions.
When something that is not a multiple of 3 is connected to something that is not a multiple of 3, the probability that it becomes a multiple of 3 is 1 in 2, so even if you stack them randomly, a surprising chain will occur.
Don't think too hard, just enjoy it.

I came up with the idea in June 2019, started building it in Unity as a programming beginner, gave up on it for 6 months due to frustration, and then managed to finish it and publish it on April 24, 2020.
Please forgive me for the strong sense of personal production in terms of direction.

There is also a "competitive sun vider" where you can play against friends.
This is easier to play.
