Defend your side through Wave 1, choose the upgrade that reduces Bishop cost after that wave, then keep deploying Bishops. A player who reached roughly Wave 30 described this exact approach on October 23, 2026. It is a documented run, not a guaranteed win or a verified final-stage solution.
Play and objective
Open Chess Survival on unityroom, made by M ike (みけ) and posted October 20, 2026. The developer describes a chess-themed game in which you defend your own side against enemy pieces. The listed session length is about ten minutes. Use the play link on the page; desktop may work better than mobile. The published description does not define a checkmate victory or a final wave.
Route from the first wave
- Start the game and focus on keeping your side safe through the first enemy wave. Watch the board instead of assuming standard chess turn rules.
- After Wave 1, look for the choice that makes Bishops cheaper. Select it when available; this is the key decision in the reported run.
- In subsequent waves, repeatedly field Bishops at the reduced cost. The reporting player explicitly credited this repeated Bishop deployment for the long run.
- Monitor threats to your defended area and decide where the next Bishop is needed. No verified tile-by-tile placement sequence has been published.
- Continue through later waves. The player reported reaching about Wave 30, and the developer replied that such longevity exceeded expectations.

| Following waves | Keep deploying Bishops | One reported run reached about Wave 30 | Firsthand player report [1] |
| Enemy breaks through | Reassess threats and Bishop placement | Sensible adjustment, not a tested guarantee | Defensive objective; editorial suggestion |
| Discount absent | Play defensively with the available choices | Retry the Bishop route later | Contingency, not a verified drop rate |
Questions players may have
Is Wave 30 the ending? No ending is documented. “Around Wave 30” is a survival milestone from one player, not a stated clear condition.
Does the Bishop upgrade always appear? Its appearance rate, precise discount and interaction with other upgrades are unknown.
What are the exact controls? The listing does not provide a key map. Follow the in-game interface rather than assuming mouse buttons or hotkeys.
Takeaway
The useful discovery is not a generic chess tip: take the Bishop discount after Wave 1 and lean into repeated cheap deployments. Treat it as a promising, player-tested survival build rather than an unbeatable recipe.
