Variant where capturing transforms the pieces

After a great deal of tinkering, testing, and refining, I'm excited to finally share Kumulus with you.

Kumulus is a chess variant I developed for a compact 7×7 board.

The unique twist is that captured pieces are not simply removed from the game. Instead, they transform, changing their form and strength.

This creates constantly evolving tactical possibilities, where every decision can shift the balance of power on the board.

The objective remains familiar: checkmate your opponent's king. The path to victory, however, is entirely new.

If you enjoy innovative strategy and board games, I would greatly appreciate your support on Kickstarter.

If you would like to try Kumulus before supporting the project, feel free to click on the link in the comments.

It's for a test app, so you can experience the game for yourself and see if it appeals to you.

Kumulus | An innovative chess variant designed by me

Hello :)

In my spare time I designed this chess variant called Kumulus. Here are some pictures of my prototype as well as the main additional game mechanics explained.

I also vibe coded a playable app, if you want to playtest it yourself. Link is in the comments.

I would appreciate your feedback. Thanks!

Welcome r/kumulus, a place to discuss an innovative tactics game

Join r/kumulus to get familiar with a new and fun chess variant I myself designed. I want to build a niche community that openly discusses the possible tactics when playing this game.

The subreddit contains already a working demo app where you can explore the game mechanics and play against a computer. I hope this can get you excited to play the game and possibly discuss it with others.

Thanks for your time :)

Aischylos‘ Abgang

Aischylos kehrte im Jahr 458 v. Chr. ein letztes Mal nach Sizilien zurück und besuchte die Stadt Gela, wo er 456 oder 455 v. Chr. starb. Valerius Maximus berichtet, dass er ausserhalb der Stadt ums Leben kam, als ein Adler eine Schildkröte fallen liess, weil er seinen kahlen Kopf für einen Felsen hielt, der geeignet wäre, den Panzer zu zerschmettern — und ihn damit tötlich traf.

Irregularity of the seasons: A metaphor for Bipolar Cycles? [Spoilers MAIN]

I’ve been thinking about the irregular seasons in A Song of Ice and Fire, and I haven’t seen this specific angle discussed in depth before:

What if the unpredictable length of summers and winters can be read as a metaphor for bipolar cycles?

Hear me out:

Summer = manic phase

Long summers in Westeros are usually associated with:

• growth, expansion, abundance

• optimism and confidence

• political overreach and lack of caution

But importantly, summer isn’t purely “good.”

It often leads to overconfidence, excess, and neglect of future risks — which feels very similar to manic episodes:

• heightened energy

• inflated confidence

• risky decisionmaking

Winter = depressive phase

Winter, on the other hand:

• brings scarcity, isolation, and death

• forces people to withdraw, conserve, and endure

• creates a constant sense of dread and survival mode

That maps surprisingly well onto depressive phases:

• reduced activity and energy

• emotional heaviness

• focus on survival rather than growth

The key: unpredictability

The most striking part isn’t just the contrast — it’s the lack of regular rhythm.

In Westeros:

• winters and summers don’t follow a stable cycle

• no one knows when they’ll start or how long they will last

This mirrors one of the defining aspects of bipolar disorder:

The unpredictability of when episodes begin and how long they persist.

A societal layer

What I find especially interesting is how this affects the culture:

• “Winter is coming” isn’t just about weather — it’s a persistent awareness of an inevitable downturn

• entire generations are shaped by how long the last “phase” lasted

• preparation vs. denial becomes a central tension

You could argue that Westerosi society lives in a constant state of:

anticipating the next “crash” after a prolonged “high”

Is this intentional?

I’m not claiming GRRM consciously wrote the seasons as a clinical metaphor.

It’s more likely that the seasons represent:

• instability

• lack of control over larger forces

• cyclical hardship

But that’s exactly why the comparison works —

because bipolar cycles are another form of living under unstable, uncontrollable extremes.

Why I think this interpretation works

• The extremes are prolonged and intense, not mild

• Both phases have upsides and downsides (summer isn’t purely good, winter isn’t purely meaningless)

• The unpredictability shapes behavior, planning, and identity

Curious what you think

• Does this add something meaningful, or is it stretching the metaphor too far?

• Are there specific characters or storylines that reflect this cycle on a more personal level?

Playtest Kumulus (a chess variant)

Yesterday, I designed an App for my chess variant, Kumulus. The game is based on my previous post here.

In this variant, chess pieces morph into different pieces after capturing opposing or your own.

What do you think? Feedback is very important to me :)
