The formation and evolution of binary star systems still remain key questionsin modern astronomy. Wide binary pairs (separations $>10^3$ AU) areparticularly intriguing because their low binding energies make it difficultfor the stars to stay gravitationally bound over extended timescales,and thusprobe the dynamics of binary formation and dissolution. Our previous SLoWPoKESI \& II catalogs provided the largest and most complete sample of wide binarypairs of low masses. Here we present an extension of these catalogs to a broadrange of stellar masses: the Gaia Assorted Mass Binaries Long Excluded fromSloWPoKES (GAMBLES), comprising 8,660 statistically significant wide pairs thatwe make available in a living online database. Within this catalog we identifya subset of 543 long-lived (dissipation timescale $>$1.5 Gyr) candidate binarypairs, of assorted mass, with typical separations between $10^3-10^{5.5}$ AU($0.002-1.5$ pc), using the published distances and proper motions from theTycho-Gaia Astrometric Solution and Sloan Digital Sky Survey photometry. Eachpair has at most a false positive probability of 0.05; the total expectation is2.44 false binaries in our sample. Among these, we find 22 systems with 3components, 1 system with 4 components, and 15 pairs consisting of at least 1possible red giant. We find the largest long-lived binary separation to benearly 3.2 pc; even so, $>76\%$ of GAMBLES long-lived binaries have largebinding energies and dissipation lifetimes longer than 1.5 Gyr. Finally, wefind the distribution of binary separations is clearly bimodal, corroboratingthe finding from SloWPoKES and suggesting multiple pathways for the formationand dissipation of the widest binaries in the Galaxy.
