Some features don’t just reward you – they Change the way you play. Rainbow Fest from Color Block Jam is one of them.It’s simple, addictive, and cleverly tied into the game’s core loop.

Looks Familiar?

How it Works?

The player needs to Beat 10 levels to activate the feature.
Once activated, it stays alive until the 1st fail.
At the start of each level, 1 random Block turns into a Rainbow (WILD) – it can be cleared from any door

Gameplay in Action

This is my 2nd favorite feature in Royal Match – right after the Core Win Streak WHY?

Because it’s NOT just a Classic Feature or LiveOps with plenty of Rewards

It’s a feature that Directly impacts the Core Gameplay – changing how each level feels and how players approach their moves

Breaking the feature down

[1] Activation

The player needs to beat 10 levels
That’s NOT exactly short or easy
As a result, the player feels they’ve truly invested effort, which makes the feature feel more valuable

[2] Rainbow Block

At the start of each level, 1 block is randomly replaced with a Rainbow (WILD) block.
Because it’s random, there’s a little lottery feeling and anticipation at the start of every level.
- sometimes it’s a simple, easy-to-clear block – nice, but not game-changing
- other times it’s a big or tricky block – which feels like a big win

[3] Losing the feature

Let’s take a closer look at what happens when the player loses it…

Lose Pop-up

In the lose pop-up, the game puts a strong emphasis on what you’re about to lose – the feature itself.

Whether it’s the Core Win Streak or Rainbow Feature – both make my Core Gameplay easier.

My thoughts as a player:

If I can’t win WITH them, there’s no way I’ll win WITHOUT them.
On top of that, if I lose them, I’ll need to play another 5-10 levels to reactivate them. And until then – I’ll be playing without any advantage.

This hooks the player on the benefits so strongly that they become the New Normal – the baseline experience. Dropping below that baseline feels like shooting yourself in the foot.

Final recommendation

If you want a truly impactful feature – make sure it Affects your Core Gameplay Experience and that the player regularly feels its impact.

But here’s the key – your level design must be adapted for these features. If you drop them in without adjustment, you risk making the game easier than it should be.
