EMBERFALL
A molten-mineshaft ball-bouncer roguelite: aim the forge and blast a stream of sparks up at descending ore, chain-shatter it into embers, and out-dig five depth-biome bosses. Draft stacking relics — Splitter, Twin Forge, Molten Core — bank embers for permanent forge upgrades, and survive the endless deep. Deterministic physics; the attract screen is the aim-bot playing for real.

Slime Grove
A Merge-Dragons-form garden puzzler where the slime IP grows up in your hands: dew drops merge into knights, kings and a LEGEND — every level proven solvable by the game's own gardener bot before you ever drag a thing.

Shanhai Gambit
山海弈 — a pixel auto chess of mythic Shan Hai Jing beasts: 8-seat bot lobby, shared pool economics, faction and element synergies, board positioning that provably matters (95% vs 53% in the harness) — every pillar of the genre turned into a machine-checked assertion.

Slimefort
Merge tower defense, born of two parents: Slime Grove's merge economy and wardrobe evolution crossed with Realmguard's machine-verified TD engine. Summon random slime recruits, drag twins together to promote them up the gear ladder, and hold the goo road — with a commander bot proving every fort winnable and a no-merge bot proving it isn't without merging.

Realmguard
Pixel kingdom tower defense: build archers, cannons, mages, frost and temples to hold three fronts against goblin hordes, flying wyrms and demon lords. Data-driven TD engine with machine-verified balance.

Boardkeep Saga
The Spirit Court expansion of Boardkeep auto chess: 68 animated pixel legends across five houses (the new 灵 SPIRIT court adds 16), living two-frame heroes that blink and sway, and a lacquered war-table stage with lanterns, moon and ink mountains — on the corrected responsive board pipeline.

PHINDEX
PHINDEX est devenu un vrai moteur de calcul déterministe autour d'un multiplicateur 64 bits (le conjugué du nombre d'or). Un onglet « Moteur de calcul » unifie trois capacités : générer une suite reproductible de valeurs, calculer un lot d'entrées (avec export CSV), et tracer pas-à-pas la formule (graine → ×m → avalanche murmuru3-style). S'y ajoutent Digest, Index & reverse-search, Multiplier Lab, Prédiction de confiance (80/90 %), et Suivi & analyse de cotes avec statistiques, tendance et risque. 100 % no-build, tout est calculé localement.

Slime Turf
A paper.io-form territory brawl: ten slimes on one arena, paint loops to claim turf, cut trails to splat rivals — with bot ecology, capture math and match health all proven headless before pixels.

VIGIL ENGINE is an original party RPG roguelike about three persistent people operating three persistent pieces of a walking shrine. A station defines the skill; every action then exchanges its operator through a fixed mechanical link before the published enemy impact lands.
Mascot Dash
3D endless runner starring the whole mascot roster: swipe through morning streets, rooftop sunsets, neon nights and dawn parks. Machine-verified obstacle patterns, unlockable runners, magnet/shield/×2 powerups.

Songbird Habitat Engine Duel
An original compact bird sanctuary card-engine game inspired by modern wildlife tableau and habitat-action board-game mechanisms.

4-key rhythm game where the music is the level: songs are pattern data, the synth performs them and the charts derive from them automatically. 4 tracks × 3 difficulties, holds, latency calibration, all machine-verified full-comboable.

Mascot Brawl
A Super-Auto-Pets-form auto battler starring the whole mascot roster: shop a squad of five, merge to level, and let deterministic brawls resolve — balance proven by four bot personalities self-playing hundreds of runs.

A touch-first mechanical guilloché puzzle. Match a faint engraved master by
