It's Black Friday. For 90 seconds everything is trying to break your store. Keep it up until midnight.

SliceBots, bugs and stolen cards. If they land, the store takes damage.
SpareReal orders. Let them drop onto the counter and get paid.

Behind the game

What you were really fighting.

Every sprite is a real Black Friday failure mode. Keeping Adobe Commerce, WooCommerce and custom PHP checkouts steady when traffic spikes is the part of commerce engineering I do for a living.

Scalper bots
Bot management and rate limiting at the edge, so real shoppers get the stock and the servers keep their breath.
Bugs in production
CI, automated tests, feature flags and a firm no-deploys-on-Friday rule. The cheapest bug is the one that never ships.
Stolen cards
Fraud screening, 3-D Secure and payment provider rules that stop chargebacks before they turn into a finance problem.
Armoured scrapers
Full-page caching, WAF rules and throttling for crawlers that hammer catalogue and price endpoints.
The DDoS botnet
CDN shielding, autoscaling, queues and graceful degradation, so the checkout survives even when the homepage is under fire.
The power-ups
Redis caching, rate limiting and a fast hotfix pipeline. The boring, dependable tools that actually win Black Friday.

Planning a big sale? Let's make sure your checkout survives it.
